Implementing the synergistic effects between metal and ligand has successfully streamlined energetics for CO2 activation gained high catalytic activities, establishing important breakthroughs in photocatalytic reduction. Herein, we describe a Ni(II) N-confused porphyrin complex (NiNCP) featuring an acidic N–H group. It is readily deprotonated exists anion form during catalysis. Owing to this functional site, NiNCP gave rise outstanding turnover number (TON) as 217,000 with 98% selectivity...
Abstract Electrochemical carbon dioxide reduction (eCO 2 R) in neutral electrolytes represents a viable solution for alleviating energy and losses associated with carbonate formation, but limited by suboptimal C 2+ selectivity productivity owing to the higher C−C coupling kinetic barrier such media. To address issue, here Cu O nanocubes are encapsulated within metalloporphyrin frameworks create benign microenvironment coupling, best catalyst of O@Cu−TCPP(Co) demonstrating maximal H 4 FE 54 ±...

Hybrid organic/inorganic composites with the organic phase tailored to modulate local chemical environment at Cu surface arise as an enchanting category of catalysts for electrocatalytic CO2 reduction reaction (CO2 RR). A fundamental understanding on how organics different functionality, polarity, and hydrophobicity affect path is, however, still lacking guide rational catalyst design.

Integrating nanostructured catalysts with semiconductors is a prevalent strategy for the design of photoelectrochemical (PEC) photocathodes toward CO2 reduction reaction (CO2RR). However, it still challenge to achieve high efficiency and selectivity due incompatible catalyst/semiconductor heterogeneous interface. Here, proposed that engineering oxygen vacancy in TiO2 interlayer plays multifunctional role boosting PEC activity CO2RR on Bi catalyst modified Si photocathode (denoted as...
Nonaqueous Li-O2 battery (LOB) represents one of the promising next-gen energy storage solutions owing to its ultrahigh density but suffers from problems such as high charging overpotential, slow redox kinetics, Li anode corrosion, etc., calling for a systemic optimization configuration and structural components. Herein, an ingenious "trinity" design LOB is initiated by implementing hollowed cobalt metal organic framework (MOF) impregnating iodized polypyrrole simultaneously cathode...
Abstract Artificial photocatalytic CO 2 reduction (CO R) holds great promise to directly store solar energy into chemical bonds. The slow charge and mass transfer kinetics at the triphasic solid–liquid–gas interface calls for rational design of heterogeneous photocatalysts concertedly boosting interfacial transfer, local concentration, exposure active sites. To meet these requirements, in this study heterostructures CdS/MOL (MOL = metal–organic layer) furnishing different redox Co sites are...
Electrocatalytic CO2 reduction (eCO2R) in acid holds promise renewable electricity-powered utilization with high efficiency, but the hydrogen evolution reaction (HER) often prevails and results a low eCO2R selectivity. Here, using cobalt phthalocyanine/Ketjen black (CoPc/KB) as model catalysts, we systematically study effect of active site density, operational current hydrated cations on acidic selectivity decipher it through componential dynamics electric double layer (EDL). The optimal...
Abstract Breaking the D 4h symmetry in square‐planar M−N 4 configuration of macrocycle molecular catalysts has witnessed enhanced electrocatalytic activity, but at expense electrochemical stability. Herein, we hypothesize that lability active Cu−N 3 motifs N‐confused copper (II) tetraphenylporphyrin (CuNCP) could be overcome by applying pulsed potential electrolysis (PPE) during carbon dioxide reduction. We find PPE can indeed enhance CH selectivity on CuNCP folds to reach partial current...
Lithiated Cu current collectors with a lean Li supply have been extensively explored as prospective composite anodes for constructing lithium metal batteries (LMBs) but suffer from low Coulombic efficiencies (CE) and uncontrollable dendrite growth.
