Food waste and food processing wastes which are abundant in nature and rich in carbon content can be attractive renewable substrates for sustainable biohydrogen production due to wide economic prospects in industries. Many studies utilizing common food wastes such as dining hall or restaurant waste and wastes generated from food processing industries have shown good percentages of hydrogen in g...

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

A robust and efficient non-precious metal catalyst for hydrogen evolution reaction is one of the key components for carbon dioxide-free hydrogen production. Here we report that a hierarchical nanoporous copper-titanium bimetallic electrocatalyst is able to produce hydrogen from water under a mild overpotential at more than twice the rate of state-of-the-art carbon-supported platinum catalyst. A...

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...

Coatings and thin film materials are employed in many different industrial fields for decades, mainly for protective purposes. This large experience provokes that, currently, a wide variety of technologies for both preparation and characterization are available. Particularly, focusing on energy and environmental applications, three main film types can be distinguished: (1) materials with cataly...

Molybdenum disulfide (MoS2) attracts attention as a highly efficient and low-cost photocatalyst for hydrogen production but suffers from low conductance high recombination rate of photogenerate...

Studies of storage and production hydrogen, which is an alternative to fossil fuels, have been intensified. Hydrogen from metal borohydrides via catalyst very attractive because its advantages, such as controlled production, high hydrogen content, nontoxicity, etc. In this study, the catalytic performances nanoporous nickel–chromium alloy nickel–vanadium catalysts prepared with magnetron sputte...

The effect of substituting native grass with jengkol (Archidendron jiringa) by-product on fermentation characteristics, rumen microbial profile, methane production, and hydrogen balance using in vitro method was investigated. Seven treatments (different composition of native grass, jengkol peel, jengkol leaves, and concentrate) with five replications in a block randomized desi...

Approved type strains of Streptococcus sanguis, S. mitis, S. mutans, and S. salivarius were grown under aerobic and anaerobic conditions. The rate of hydrogen peroxide excretion, oxygen uptake, and acid production from glucose by washed-cell suspensions of these strains were studied, and the levels of enzymes in cell-free extracts which reduced oxygen, hydrogen peroxide, or hypothiocyanite (OSC...
