Abstract Iron phthalocyanine (FePc) is a promising non-precious catalyst for the oxygen reduction reaction (ORR). Unfortunately, FePc with plane-symmetric FeN 4 site usually exhibits an unsatisfactory ORR activity due to its poor O 2 adsorption and activation. Here, we report axial Fe–O coordination induced electronic localization strategy improve adsorption, activation thus performance. Theoretical calculations indicate that evokes among direction of O–FeN sites enhance To realize this...
Abstract Developing high-performance electrocatalysts toward hydrogen evolution reaction is important for clean and sustainable energy, yet still challenging. Herein, we report a single-atom strategy to construct excellent metal-organic frameworks (MOFs) electrocatalyst (NiRu 0.13 -BDC) by introducing atomically dispersed Ru. Significantly, the obtained NiRu -BDC exhibits outstanding activity in all pH, especially with low overpotential of 36 mV at current density 10 mA cm −2 1 M phosphate...

Abstract Electrochemical production of hydrogen peroxide (H 2 O ) through two‐electron (2 e − oxygen reduction reaction (ORR) is an on‐site and clean route.

Atomically dispersed FeN4 catalysts have been considered as potential materials to replace Pt-based for the oxygen reduction reaction (ORR), but they often suffer from sluggish O2 activation kinetics due symmetrical charge distribution. Herein, we introduce external N, including pyrrolic-N (PN) and graphitic-N (GN), an electron acceptor near regulate its distribution improve ORR activity. Theoretical calculations reveal that introduction of PN evokes much enhanced redistribution local...
Abstract Designing and synthesizing efficient molecular catalysts may unlock the great challenge of controlling CO 2 reduction reaction (CO RR) with precision. Nickel phthalocyanine (NiPc) appears as a promising candidate for this task due to its adjustable Ni active‐site. However, pristine NiPc suffers from poor activity stability RR owing adsorption activation at bare site.

Excessive consumption of fossil fuels gives rise to the increasing emission carbon dioxide (CO 2 ) in atmosphere and furthers ecocrisis. Electrochemical CO reduction (ECR) has both functions dwindling greenhouse gas concentration converting it into valuable products. Due intrinsic chemical inertness molecules, study on efficient low‐cost catalysts attracted much attention. Recently isolated atoms, dispersed stable support, play an important role decreasing energy barriers intermediate steps...
