Abstract Developing efficient and low‐cost replacements for precious metals as electrocatalysts active in electrochemical reactions—the oxygen evolution reaction (OER), hydrogen (HER), reduction (ORR)—is a top priority renewable energy technology. In this work highly very stable trifunctional electrocatalyst composed of Co 2 P embedded Co, N, multi‐doped carbon has been synthesized using zeolitic imidazolate frameworks precursors. The synergistic effects between the multi‐heteroatom‐doped...
Exploring sustainable and high-performance electrocatalysts for the oxygen reduction reaction (ORR) is crucial issue large-scale application of fuel cell technology. A new strategy demonstrated to utilize biomass resource synthesis N-doped hierarchically porous carbon supported single-atomic Fe (SA-Fe/NHPC) electrocatalyst toward ORR. Based on confinement effect high-coordination natural iron source, SA-Fe/NHPC, derived from hemin-adsorbed bio-porphyra-carbon by rapid heat-treatment up 800...
Abstract As byproducts of the meat‐processing industry, nearly 100 million tons bones, skin, and scales are generated from livestock, poultry, fish every year generally discarded as waste. However, these widespread low‐cost biomass materials rich in collagen that is primarily composed elements C, N, O, S. By controlled pyrolysis, collagen‐enriched can be transformed into biomass‐derived porous carbons (BPCs). The ordered biotic structures specific elemental compositions natural precursors...
Abstract High‐performance electrocatalysts for the hydrogen evolution reaction (HER) have an important role to play in development of renewable energy. Platinum remains most efficient known HER electrocatalyst. Therefore, it is necessary find ways maximize Pt utilization actual practical applications.

Bimetal nitrogen-doped carbon with both Fe and Co, derived from the pyrolysis of iron cobalt phthalocyanine-based conjugated polymer networks, possesses a few-layer graphene-like texture hierarchical porosity in meso/micro multimodal pore size distribution. The novel electrocatalyst exhibits Pt-like catalytic activity much higher durability for oxygen reduction.
Rational design of porous structure is an effective way to fabricate the nonprecious metal electrocatalysts (NPMCs) toward oxygen reduction reaction (ORR) with high activity comparable or even superior Pt-based electrocatalysts.

The resultant Co,N-HCNP electrocatalyst possesses unique...
Developing high-performance bifunctional electrocatalysts for oxygen reduction reaction (ORR) and evolution (OER) is of vital importance in energy storage conversion systems.
