An outstanding pH-universal bifunctional electrocatalyst is developed using a novel TMAAE strategy with departure of Br-species attached to the Co–N<sub>4</sub>macrocycle.
Catalysts used for the oxygen reduction reaction (ORR) are crucial to fuel cells. However, development of novel catalysts possessing high activity at a low cost is very challenging. Recently, extensive research has indicated that nitrogen-doped carbon materials, which include nonprecious metals as well metal-based oxides, can be excellent candidates ORR. Here, Co/Co3O4@N-doped (NC) with and highly stable performance utilized an ORR electrocatalyst through pyrolysis easily prepared physical...
Iron, N-codoped carbon materials (Fe-N-C) are promising electrocatalysts toward oxygen reduction reactions due to their high atom utilization efficiency and intrinsic activity. Nanostructuring of the Fe-N-C materials, such as introducing porosity into structure, would be conducive further increasing exposure active sites well improving mass transfer. Herein, we explore potential iron complex-functionalized micelles mesoporous SiO2 a platform for constructing porous materials. The classical...
Stable dispersions of paraffin wax droplets and their nano- microspheres have broad applications. Despite intensive efforts, the production uniform spheres remains a challenge. For preparation, abundant surfactants other additives are commonly used to stabilize dispersions. These hardly removable entrain often adverse consequence in many applications, particularly biological medical where with absolutely clean surface preferred. We report here novel process prepare stable dispersion...
An iron cation double isolated strategy is applied to construct Fe, N‐containing porous biomass carbon oxygen reduction reaction (ORR) electrocatalysts. Two different activating agents, Zn(NO 3 ) 2 and ZnCl , are used respectively, using one‐pot co‐pyrolysis over the rangooncreeper fruit (RF) template absorbed with Fe‐PPy (Fe 3+ ‐bonded by polypyrrole matrix) Fe‐bipyridine 2,2‐bipyridine ligands). It found that resulting product ‐Fe/C/N@bio‐C provides bigger specific area higher mesoporous...
Abstract A novel “dual isolation of metal active sites” heterojunction engineering is developed in this work. The double the sites achieved through MN 4 (M = Co, Fe) coordinating bonds sulfonated‐substituted metalloporphyrin (MTPPS) and electrostatic interactions MTPPS absorbed with poly(3,4‐ethylenedioxythiophene) networks. Subsequent “in situ copyrolysis” over precursors ensures effective contact between p‐type CoFe 2 O n‐type Fe 3 species N,S‐doping carbon support, respectively. This...
The Fe/S/N–C electrocatalyst developed from polythiophene protected poly-porphyrin displays an overall superior electrocatalytic activity for the ORR and zinc–air batteries.
Activatable triplet photosensitization refers to a photosentization process which can be turned on/off easily by external stimulus. photosensitizations are normally achieved interfering with the singlet excited state before intersystem cross (ISC), i.e., formation of states sensitizer. To achieve novel activatable photosensitization, disulfide-bridged porphyrin zinc(II) dyad (ZnPor–S–S–ZnPor) is prepared. Although fast ISC conducted in this dyad, an extremely low efficiency obtained when...

In order to promote the wide application of clean energy-fuel cells, it is urgent develop transition metal-based high-efficiency oxygen reduction reaction (ORR) catalytic materials with a low cost and available rich raw material resources replace currently used precious metal platinum-based materials. Herein, novel 'active-site-anchoring' strategy was developed synthesize highly-activated carbon-based ORR catalysts. Firstly, poly(p-phenylene benzobisoxazole) (PBO) fiber stable chemical...
A facile pre-anchored approach is employed to prepare a non-precious bifunctional electrocatalyst Co2P@Fe(PO3)2-NCNT with p−n heterojunction structure for the oxygen reduction reaction (ORR) and evolution (OER). Firstly, well-designed Co3O4/Fe(CN)64−@PPy-CNT precursor synthesized via an one-pot method, in which Fe(CN)64− Co3O4 are on polypyrrole (PPy) chains that in-situ formed carbon nanotubes (CNTs). Subsequent pyrolysis phosphating of resulted catalyst, contains highly dispersed Co2P...
