چکیده

Water electrolysis is promising for industrial hydrogen production to achieve a sustainable and green economy, but the high cost of technology limits its market share. Developing efficient yet economic electrocatalysts crucial decrease electricity electrolytic cell. Meanwhile, in seawater electrolyte can further reduce feedstock cost. Here, type electrocatalyst synthesized, where trace precious metals are strongly anchored on corrosion-resistive matrix. As an example, produced Pt/Ni-Mo only needs overpotential 113 mV reach ultrahigh current density 2000 mA cm?2 saline-alkaline electrolyte, demonstrating best performance reported thus far. It shows activity long durability various electrolytes under harsh conditions, including strong alkaline simulated electrolytes, elevated temperatures up 80 °C. This large scale at low good commercial membrane electrode assembly stack, feasibility practical water electrolysis.

Water splitting-biosynthetic system with CO₂ reduction efficiencies exceeding photosynthesis.

Artificial photosynthetic systems can store solar energy and chemically reduce CO2 We developed a hybrid water splitting-biosynthetic system based on a biocompatible Earth-abundant inorganic catalyst system to split water into molecular hydrogen and oxygen (H2 and O2) at low driving voltages. When grown in contact with these catalysts, Ralstonia eutropha consumed the produced H2 to synthesize b...

When NiO@Ni Meets WS2 Nanosheet Array: A Highly Efficient and Ultrastable Electrocatalyst for Overall Water Splitting

The development of low-cost, high-efficiency, and stable bifunctional electrocatalysts toward the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is of paramount importance for large-scale water splitting. Here, we develop a new strategy for the first design and synthesis of a NiO@Ni decorated WS2 nanosheet array on carbon cloth (NiO@Ni/WS2/CC) composite. This composite se...

Hollow ternary PtPdCu nanoparticles: a superior and durable cathodic electrocatalyst.

Hollow alloyed nanoparticles (NPs) represent one kind of promising fuel cell electrocatalyst. However, the formation of single-cavity hollow structures by a dealloying process is quite challenging owing to the random leaching/dissolution of transition metals, surface passivation and the limited diffusion distance of the noble metals. Here we present a facile method to prepare hollow PtPdCu NPs ...
