Developing high-active and low-cost bifunctional materials for catalyzing the hydrogen evolution reaction (HER) oxygen (OER) holds a pivotal role in water splitting. Therefore, we present new strategy to form NiS/Ni2P heterostructures. The as-obtained NiS/Ni2P/carbon cloth (CC) requires overpotentials of 111 mV HER 265 OER reach current density 20 mA cm-2, outperforming their counterparts such as NiS Ni2P under same conditions. Additionally, NiS/Ni2P/CC electrode 1.67 V cell voltage deliver...

Abstract Algal biofuel is regarded as one of the ultimate solutions for renewable energy, but its commercialization hindered by growth limitations caused mutual shading and high harvest costs. We overcome these challenges advancing machine learning to inform design a semi-continuous algal cultivation (SAC) sustain optimal cell minimize shading. An aggregation-based sedimentation (ABS) strategy then designed achieve low-cost biomass harvesting economical SAC. The ABS achieved engineering...
A deposition process has been developed to fabricate a complete-monolayer Pt coating on large-surface-area three-dimensional (3D) Ni foam substrate using buffer layer (Ag or Au) strategy. The quartz crystal microbalance, current density analysis, cyclic voltammetry integration, and X-ray photoelectron spectroscopy results show that the monolayer accomplishes full coverage can be controlled single atomic thickness. To our knowledge, this is first report 3D bulk with complex fine structures;...
Overall water splitting is an attractive technology to produce clean hydrogen and oxygen. In this study, we constructed amorphous NixCoy layered double hydroxide (LDH) hybridized with three-dimensional NiCo2O4 fabricate a core–shell nanowire array on Ni foam (NiCo2O4@NixCoy LDH/NF) as highly efficient electrocatalyst for overall electrolysis. By tuning the Ni/Co molar ratio in LDH, extremely low overpotentials of 193 mV oxygen evolution reaction (OER) 115 (HER) at current density 10 mA cm–2...
Due to the precisely controllable size, shape, and composition, self-assembled nanocrystal superlattices exhibit unique collective properties find wide applications in catalysis energy conversion. Identifying their intrinsic electrocatalytic activity is challenging, as averaged on ensembles can hardly be dissected from binders or additives. We here report direct measurement of oxygen evolution reaction at single superparticles ∼8 nm NiFe2O4 and/or ∼4 Au nanocrystals using scanning...
The development of chiral ligands to fine-tune the stereocontrol has been recognized as a crucial pillar asymmetric catalysis. In contrast well-developed pyridine–pyridine-type and pyridine–oxazoline-type ligands, oxazole–pyridine-type have rarely exploited. this study, class [2.2]paracyclophane-based planar-chiral oxazole–pyridine N,N-ligands designed synthesized. These presented superior performance in enantioselective palladium-catalyzed acetoxylative cyclization alkyne-tethered...
The direct double dehydrogenation from primary amines to nitriles without an oxidant or hydrogen acceptor is both intriguing and challenging. In this paper, we describe a non-noble metal catalyst capable of realizing such transformation with high efficiency. A cobalt-centered N,N-bidentate complex was designed employed as metal–ligand cooperative catalyst. Detailed kinetic studies, control experiments, DFT calculations revealed the crucial hydride transfer, proton evolution processes....
Density functional theory (DFT) calculations have been conducted to investigate the mechanism of cobalt(II) tetraamino phthalocyanine (CoPc-NH2) catalyzed electro-reduction CO2.
