Microbes recycling nutrient and detoxifying ecosystems are capable to fulfil the future energy need by producing biohydrogen by due to the coupling of autotrophic and heterotrophic microbes. In granules microbes mutualy exchanging nutrients and electrons for hydrogen production. The consortial biohydrogen production depend upon constituent microbes, their interdependence, competition for resources, and other operating parameters while remediating a waste material in nature or bioreactor. The present review deals with development of granular algae-bacteria consortia, hydrogen yield in coculture, important enzymes and possible engineering for improved hydrogen production.

Electrocatalytic dehalogenative deuteration is a sustainable method for precise deuteration, whereas its Faradaic efficiency (FE) is limited by a high overpotential and severe D evolution reaction (DER). Here, Cu site-adjusted adsorption and crown ether-reconfigured interfacial DO are reported to cooperatively increase the FE of dehalogenative deuteration up to 84% at -100 mA cm. Cu sites strengthen the adsorption of aryl iodides, promoting interfacial mass transfer and thus accelerating the kinetics toward dehalogenative deuteration.

Hydrogen production via water-splitting or ammonia electrolysis using transition metal-based electrodes is one of the most cost-effective approaches. Herein, ca. 1-4% of Pt atoms are stuffed into a wolframite-type NiWO lattice to improve the electrocatalytic efficiency.

Seawater electrolysis has emerged as a promising approach for the generation of hydrogen energy, but the production of deleterious chlorine derivatives (e.g., chloride and hypochlorite) presents a significant challenge due to the severe corrosion at the anode.

ConspectusThe discovery of reversible hydrogenation using metal-free phosphoborate species in 2006 marked the official advent of frustrated Lewis pair (FLP) chemistry. This breakthrough revolutionized homogeneous catalysis approaches and paved the way for innovative catalytic strategies. The unique reactivity of FLPs is attributed to the Lewis base (LB) and Lewis acid (LA) sites either in spatial separation or in equilibrium, which actively react with molecules.

Metal-catalyzed hydrogen isotope exchange (HIE) has become a valuable method for incorporating deuterium and tritium into organic molecules, with applications in a wide range of scientific fields. This study explores the role of transition metal cooperativity in enhancing catalytic hydrogen/deuterium (H/D) exchange using early-late heterobimetallic polyhydride (ELHB) complexes. A series of four ELHB complexes, of general formula [M(CHBu)(H)M'Cp*], combining early transition metals (M = Hf, Ta) with late metals (M' = Ir, Os), were synthesized and evaluated for their catalytic activity in HIE of (hetero)arenes.
