Synthesis, Purification, and Electrocatalytic Activity of Platinum Nanocatalyst with Globular Dendritic Structure

open access: yes, 2012
A new Pt nanocatalyst was synthesized by chemical reduction of K2PtCl4 by ascorbic acid in the presence of a non-ionic surfactant Brij-35 (CH3(CH2)(10)CH2(OCH2CH2)(23)OH) in aqueous solution at room temperature.

CO2 Conversion Into Energy Rich Fuels Over Nascent COF Decorated‐Lead Free Halide Perovskites Hybrid Nano Catalysts: Experimental and Computational Investigation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A panoramic scheme signifies the CO2 conversion into energy‐rich fuels over nascent COF‐decorated lead‐free halide perovskite hybrid nano‐catalysts. Even though lead‐containing halide perovskites have been deemed emerging materials. However, the presence of toxic and carcinogenic lead (Pb) metal, small surface area, low charge separation, and a high ...

Se‐Vacancy Engineering Enables Dual Electronic and Interfacial Regulation in SnSe2 Nanocatalysts for High‐Performance Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Se vacancies in SnSe2 induce local electron redistribution and create unsaturated Sn sites, enabling a switch from single‐site to dual‐site adsorption of lithium polysulfides. This structure synergistically enhances redox kinetics, accelerates sulfur conversion, suppresses the shuttle effect, reduces polarization, and significantly improves the ...
