Boosting the hydrogen evolution reaction in an alkaline environment by enhancing activity of Pd nanoparticles exploiting unique redox ZrO 2 .

In article number 2100141, Jie Ding, Baojun Li, Yushan Liu and co-workers, inspired by the glazing of elegant secret Celadon, design a solid-phase interfacial reaction strategy to prepare hydrogen evolution catalysts. Highly active Ru metal nanoparticles are localized onto MoO2-VO plane. This report provides versatile platform for preparation multi-component catalysts with high total activity.

Small size molybdenum carbides (2.5 nm for MoC and 5.0 nm for Mo2C) with clean surface on graphene were prepared for efficient and stable hydrogen evolution reaction catalysts.

Metal chalcogenides, and doped molybdenum sulfides in particular, have considerable potential as earthabundant electrocatalysts for the hydrogen evolution reaction. This is especially true in the case of solar-tohydrogen devices, where an ability to deposit these materials on transparent substrates is therefore desirable. Hydrothermal methods are perhaps the most common route by which metal cha...

The carbon dioxide reduction reaction (CO2RR) in aqueous electrolytes suffers from efficiency loss due to the competitive hydrogen evolution (HER). Developing efficient methods suppress...

1.. After 2 hours of fermentation in nitrogen the metabolism of those algae which were found capable of photoreduction with hydrogen changes in such a way that molecular hydrogen is released from the cell in addition to carbon dioxide. 2. The amount of hydrogen formed anaerobically in the dark depends on the amount of some unknown reserve substance in the cell. More hydrogen is formed in presen...

alkali and alkaline earth metals hydrogen sulfate catalyzed the one-pot three component condensation reactions of aldehydes, 1,3-dicarbonyl compounds and urea or thiourea under solvent-free conditions leading to 3,4-dihydropyrimidin-2(1h)-ones in high yields at 80 °c. our results showed that biginelli reaction not only is ph dependent, but the cation of catalyst plays an important role.

The major challenge of photocatalytic water splitting, the prototypical reaction for the direct production of hydrogen by using solar energy, is to develop low-cost yet highly efficient and stable semiconductor photocatalysts. Herein, an effective strategy for synthesizing extremely active graphitic carbon nitride (g-C3N4) from a low-cost precursor, urea, is reported. The g-C3N4 exhibits an ext...
