Elaborate design of highly active and stable catalysts from Earth-abundant elements has great potential to produce materials that can replace the noble-metal-based commonly used in a range useful (electro)chemical processes. Here we report, for first time, synthetic method leads situ growth {2̅10} high-index faceted Ni3S2 nanosheet arrays on nickel foam (NF). We show resulting material, denoted Ni3S2/NF, serve as active, binder-free, bifunctional electrocatalyst both hydrogen evolution...
Developing efficient, durable, and earth‐abundant electrocatalysts for both hydrogen oxygen evolution reactions is important realizing large‐scale water splitting.

A plasma oxidation method is developed to fabricate atomic-scale pores in the basal planes of electrochemically inert TaS2 nanosheets functionalize 2D crystals with high electrocatalysis for hydrogen evolution reaction. Quantitative measurements under-coordinated atoms at edges by aberration-corrected transmission electron microscopy reveal intrinsic correlation between defective atomic sites and electrocatalytic activities .

Abstract The oxygen evolution reaction (OER) is a bottleneck process for water splitting and finding highly efficient, durable, low‐cost, earth‐abundant electrocatalysts still major challenge. Here sulfur‐treated Fe‐based metal–organic‐framework reported as promising electrocatalyst the OER, which shows low overpotential of 218 mV at current density 10 mA cm −2 exhibits very Tafel slope 36.2 dec −1 room temperature. It can work on high densities 500 1000 overpotentials 298 330 mV,...
Abstract Developing earth‐abundant and efficient electrocatalysts for photoelectrochemical water splitting is critical to realizing a high‐performance solar‐to‐hydrogen energy conversion process. Herein, phosphorus‐rich colloidal cobalt diphosphide nanocrystals (CoP 2 NCs) are synthesized via hot injection. The CoP NCs show Pt‐like hydrogen evolution reaction (HER) electrocatalytic activity in acidic solution with small overpotential of 39 mV achieve −10 mA cm −2 very low Tafel slope 32 dec...
With the advantage of high catalytic activity metal clusters from abundant uncoordinated atoms and interfacial electron interaction between metal/metal oxides, cluster/metal oxide hybrids have great potential in catalysis been attracting more attention recent years. In this work, sub-nanometer sized palladium accommodated into porous ceria were successfully synthesized. The characterizations high-resolution transmission microscopy (HRTEM) extended X-ray absorption fine structure (EXAFS)...
Designing highly active, stable, and cost-efficient electrocatalysts as alternatives to replace Pt is extremely desirable for hydrogen evolution reaction (HER). Despite much progress that has been made based on complete nonprecious metals (NPMs), very few NPM catalysts have shown comparable performance Pt-based catalysts. Herein, a cost-efficient, environmentally friendly, scalable method synthesize novel ruthenium(Ru)-doped transition-metal carbide (Mo2C) hybrid catalyst was proposed. The...
Developing economical, efficient, and earth-rich electrocatalysts for hydrogen evolution reaction (HER) is quite challenging ideal. We propose that [P2W18O62]6– as the guest, due to its excellent reversible 18 electron-transfer capacity redox properties, then TM-BDC (TM = Ni, Co, Fe, BDC 1,4-benzene-dicarboxylate) host make packaged not escape porous structure.

Introduction Proton Exchange Membrane (PEM) water electrolysis provides a sustainable solution for the production of hydrogen, and is well suited to couple with intermittent nature energy sources such as wind solar. To spur large-scale commercial application PEM electrolysis, more efficient less expensive non-noble metal electrocatalysts towards hydrogen evolution reaction (HER) are required. Recently, transition phosphides (TMPs) have become typical representatives burgeoning HER due that...
