TL;DR: In this paper, a 3D-ordered macroporous (3DOM) La1−xKxCoO3 (x = 0-0.3) perovskite-type oxide catalysts with large pore sizes and interconnected macroporic frameworks were successfully synthesized by a novel method of carboxy-modified colloidal crystal templates (CMCCT).

TL;DR: In this article, large-sized two-dimensional phosphorus-doped carbon nanosheets (2D-PPCN) with tunable porosity were synthesized via a multifunctional templating method.
Abstract: Large-sized two-dimensional phosphorus-doped carbon nanosheets (2D-PPCN) with tunable porosity were synthesized via a multifunctional templating method A single inexpensive solid precursor, phosphorus pentoxide, is combined with common saccharides in a stepwise multiple templating process for 2D construction, phosphorus doping, and regulated micro-/mesopore creation This reliable 2D porous carbon production technique can potentially be utilized in a variety of energy storage and conversion fields The effects of different porous structures on the electrocatalytic activity of 2D-PPCN based electrocatalysts are specifically investigated in this work The interconnected open-pore system and high specific surface area result in a high catalytic efficiency for both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) When integrated into an air-breathing cathode for rechargeable Zn-air batteries, the best-performing 2D-PPCN demonstrates better cell performance than a noble metal benchmark

TL;DR: In this paper, the codeposition behavior of three alloy systems, FeNi, FeCo, and CoNi, was studied in acid sulfate electrolytes using rotating cylinder electrodes to control mass transport conditions.
Abstract: The codeposition behavior of three alloy systems, FeNi, FeCo, and CoNi, was studied in acid sulfate electrolytes using rotating cylinder electrodes to control mass transport conditions The partial current densities of the codepositing metals and of the side reaction were determined from an analysis of the deposit and were compared with those measured for the pure metals deposited under identical conditions Results confirmed that Ni is inhibited by the presence of and ions Fe deposition rate is enhanced by the presence of and ions The ion of the less noble metal has a stronger influence on the deposition behavior of the partner ion Co is inhibited by codeposition of ions and enhanced by ions The present data demonstrate that anomalous codeposition of iron group metals involves both inhibiting and accelerating effects © 1999 The Electrochemical Society All rights reserved
