Description
Technical field
The present invention relates to the catalyst of a kind of photocatalysis Decomposition hydrogen sulfide hydrogen manufacturing and the regeneration of catalyst, belong to photocatalysis and produce the energy field of hydrogen and the environmental area of the hydrogen sulfide gas that photocatalysis Decomposition is harmful to.
Background technology
Along with the global economy high speed development, energy demand increases rapidly, causes world energy sources production and environmental bearing capacity can't bear the heavy load.Problems such as increasingly serious environmental pollution and climate change, and high energy prices have not only increased the weight of the load of development of world economy, bring increasing puzzlement also for the life of ordinary people.Hydrogen sulfide is the byproduct of Chemical Manufacture, petroleum refining and natural gas processing process, be a kind of stench, severe toxicity and have corrosive sour gas, with its direct discharging not only can etching apparatus, contaminated environment, also may jeopardize people's life, also cause the significant wastage of resource simultaneously.Photocatalysis Decomposition hydrogen sulfide is under the semiconductor catalyst effect, utilizes abundant and cheap and easy to get solar energy to produce hydrogen as the energy source decomposing hydrogen sulfide, has not only solved problem of environmental pollution, and solar energy is collected and stored with the form of Hydrogen Energy.Photochemical catalyst commonly used at present has: CdS photochemical catalyst, composite photo-catalyst, multi-element metal sulfide photocatalyst, loaded photocatalyst etc., obtained very big progress, but still have very big distance from practical application, exist a lot of technical barriers to need to solve, the inactivation of catalyst is exactly one of them.So development is efficient, cheap, free of contamination semiconductor light-catalyst is the recycling of the key of photocatalysis Decomposition hydrogen sulfide hydrogen manufacturing, especially catalyst.
Titanium dioxide (TiO
2) have good, the anti-photoetch of chemical stability, advantage such as nontoxic, have higher using value and research prospect in photocatalysis field.Graphene (Graphene) is because electrochemical properties and the good electrical conductivity and the chemical stability of unique nanostructured, excellence are the multifunctional materials of a kind of good electronics or hole-transfer.Titanium dioxide-Graphene composite photocatalyst material has potential application prospect in photocatalysis field.
Summary of the invention
The objective of the invention is in order to design a kind of Regenrable catalyzed dose in the hydrogen manufacturing of photocatalysis Decomposition hydrogen sulfide.Be specifically related to adopt titanium dioxide-graphene oxide (TiO
2-GO) composite catalyst carries out photocatalysis Decomposition hydrogen sulfide, and catalyst still keeps higher photocatalytic activity by recycling.
Method of the present invention is water or sodium hydrate aqueous solution absorbing hydrogen sulphide gas, adopts TiO
2-GO composite nano materials is as photochemical catalyst, and light source is the metal halid lamp of approximate solar spectrum, is carrying out the hydrogen manufacturing of photocatalysis Decomposition hydrogen sulfide except that under the oxygen condition.And and TiO
2Carried out the contrast experiment as photochemical catalyst.
Described method is that sample solution adopts the illumination of metal halid lamp all band, and with the amounts of hydrogen that gas chromatographic detection produces, behind the continuous illumination 12h, leads to hydrogen sulfide gas again in second day, carries out continuing illumination 12h after the deoxygenation.Along with the prolongation of light application time, the hydrogen-producing speed of sample solution reduces.Repeat above-mentioned experiment, produce until almost detecting less than hydrogen.
Described method is that the sample solution that with catalysqt deactivation, no longer produces hydrogen desolvates by centrifugal removing, and reclaims catalyst, and with organic solvent washings such as carbon tetrachloride, drying.
Described method is the TiO that will reclaim
2-GO and TiO
2Catalyst carries out photocatalysis Decomposition hydrogen sulfide hydrogen manufacturing experiment again, and other condition is constant.
Experimental result shows, all systems are along with the prolongation of light application time, and the amount and the hydrogen-producing speed that produce hydrogen all reduce, after the 3rd day or the 4th day, almost no longer produce hydrogen or produce amounts of hydrogen seldom (Fig. 1, Fig. 2, Fig. 3).This is because the surface that sulfidal that generates in the course of reaction or polysulfide have been coated on catalyst granules causes catalysqt deactivation.For the system of sodium hydrate aqueous solution absorbing hydrogen sulphide, hydrogen output and hydrogen-producing speed all are better than only being the system of the aqueous solution, and this is that sulphur is mainly with HS because the NaHS that generates in the system is a strong base-weak acid salt
-The form of ion exists, and help the reaction of photocatalysis Decomposition hydrogen sulfide hydrogen manufacturing, and hydrogen sulfide mainly is with H in the aqueous solution
2The S molecular forms exists.In addition, in hydrogen sulfide solution, under the identical situation of other condition, adopt TiO
2-GO composite catalyst, hydrogen-producing speed compares TiO
2Catalyst improved about 2.5 times (Fig. 1, Fig. 3).
TiO through regeneration
2-GO catalyst, no matter be at the NaHS aqueous solution or in hydrogen sulfide solution, photocatalysis Decomposition hydrogen sulfide hydrogen manufacturing experiment still keeps higher hydrogen output and hydrogen-producing speed, reached more than 90% of original catalyst (Fig. 4, Fig. 5).This is owing to TiO in this composite catalyst
2Nano particle is distributed in the Graphene surface of stratiform, be not easy to reunite in the illumination process, so its surface coated sulfidal and polysulfide is easy to be removed by solvent wash, thereby has recovered photocatalytic activity basically.And use the TiO that reclaims with quadrat method
2Catalyst carries out the illumination experiment again in hydrogen sulfide solution, its hydrogen output reduces (Fig. 6) greatly.This is because TiO
2Nano particle is reunited in photocatalytic process easily, is bundled together with the sulfidal and the polysulfide that generate, can not be removed by simple washing methods.
Outstanding meaning of the present invention is:
1, titanium dioxide-graphene oxide composite photo-catalyst is easily removed the elemental sulfur that generates in the photocatalysis Decomposition hydrogen sulfide process, can regenerate, through recycling, still keep higher photocatalytic activity, hydrogen generation efficiency reaches more than 90% of original catalyst.And the method for regeneration is simple, and cost is low.
2, adopt titanium dioxide-graphene oxide composite material photocatalyst, hydrogen-producing speed has improved about 2.5 times than titanium deoxide catalyst;
3, the sunshine that receives of the spatial distribution of metal halid lamp and earth surface is closely similar, can better analog solar;
