A Br-regulated transition metal active-site anchoring and exposure strategy in biomass-derived carbon nanosheets for obtaining robust ORR/HER electrocatalysts at all pH values

A novel Br-regulated "Transition Metal Active-site Anchoring and Exposure" (TMAAE) strategy is reported, for the first time, to fabricate a hierarchical porous Co/N-doped bio-carbon bifunctional electrocatalyst (CoTBrPP?bio-C) for an all-pH ORR and HER by using a simple one-pot co-pyrolysis over a mushroom (MR) template with adsorbed Br-substituted porphyrinato cobalt (CoTBrPP). Introduction of CoTBrPP onto the MR template not only leads to a larger specific area of 604 m2 g-1 in CoTBrPP?bio-C relative to that of CoTPP?bio-C (CoTPP = Br-free CoTBrPP), 98 m2 g-1, but more importantly also regulates the oriented distribution of pores precisely which promotes effective exposure of multiple active sites depending on the departure of Br-species attached to the Co-N4 macrocycle periphery. Impressively, CoTBrPP?bio-C with a Co loading down to 0.77 at% exhibits higher all-pH ORR and HER performance compared to CoTPP?bio-C with a Co loading of 3.5 at%. An efficient TMAAE makes CoTBrPP?bio-C possess higher onset and half-wave potentials of 0.93 and 0.85 V for the ORR, and a smaller Tafel slope of 80 mV dec-1 for the HER in an alkaline medium. CoTBrPP?bio-C also had a superior all-pH long-term stability and outstanding methanol tolerance, surpassing commercial Pt/C and most non-precious-metal catalysts reported to date. Furthermore, Zn-air batteries assembled with CoTBrPP?bio-C exhibited a higher peak power density of 100 mW cm-2 and excellent durability than Pt/C.

Super absorbent conjugated microporous polymers: A synergistic structural effect on the exceptional uptake of amines

Conjugated microporous polymers exhibit a synergistic structural effect on the exceptional uptake of amines, whereas the dense porphyrin units facilitate uptake, the high porosity offers a large interface and the swellability boosts capacity. They are efficient in the uptake of both vapor and liquid amines, are applicable to various types of amines, and are excellent for cycle use.
