Microorganisms can produce hydrogen gas (H(2)) at high rates by fermentation of carbohydrates, but not from proteins. However, it is possible to produce H(2) at high rates and yields from proteins by electrohydrogenesis in microbial electrolysis cells (MECs). Hydrogen gas was generated using bovine serum albumin (BSA, 700 mg/L) in a single-chamber MEC at a rate of Q=0.42+/-0.07 m(3)/m(3)/day an...

The photochemistry of the hydrogen-bonded oxotitanium porphyrin-water complex (TiOP-H(2)O) has been explored with electronic-structure calculations. It is shown that intramolecular charge-transfer processes, which are initiated by the excitation of the Soret band of TiOP, accumulate electronic charge on the oxygen atom of TiOP, which in turn abstracts a hydrogen atom from water by an exoenerget...

Pharmaceutical industry often generates highly toxic wastewater and sludge depending upon the used manufacturing process and season. The high BOD to COD ratio of this particular wastewater makes biological treatment difficult. Hence chemical treatment proves to be a useful option. Fenton’s reagent is used in the treatment of pharmaceutical industry wastewater in this study. The ferrous and hydr...

The work presented here, demonstrates the on-board exhaust assisted catalytic ammonia (NH3) conversion to H2-N2 using either only heat (decomposition) or by direct reaction with part of gas (reforming). resultant mixture from driven thermochemical energy recovery processes contains up 15% more than reactant NH3 (i.e. for 1 kW used in 1.15 H2 is produced). Experimental studies a rhodium-platinum...

Abstract Pt-WO 3 composite nanoceramic produced by pressed and sintered with 5 wt% Pt WO nanoparticles has a response multiple of about 80 for 800 ppm H 2 -20% O -N 10 100 at room temperature 40 relative humidity(RH), showing an impressive sensing capacity low concentration hydrogen. However, will show the aging phenomenon mainly rapid decline recovery rate in open air, which limits its applica...
