Selective Recovery of Battery‐Grade Li2CO3 from Spent NCM Cathode Materials Using a One‐Step Method of CO2 Carbonation Recovery Without Acids or Bases

A one-step method of CO2 carbonation recovery technology: the selective leaching of Li from spent NCM cathode materials by carbonation reduction process and the recovery of battery-grade Li2CO3 by a simple concentration precipitation process without acids or bases. Abstract The recovery of spent lithium-ion batteries by traditional acid leaching...

Magnetically Recyclable Borane Lewis Acid Catalyst for Hydrosilylation of Imines and Reductive Amination of Carbonyls

Fluorinated arylborane-based Lewis acid catalysts have shown remarkable activity and serve as ideal examples of transition metal-free catalysts for diverse organic transformations. However, their homogeneous nature poses challenges in terms of recyclability and separation from reaction mixtures. This work presents an efficient technique for the heterogenization...

Monitoring the Morphological Changes of Skeleton‐PtCo Electrocatalyst during PEMFC Start‐Up/Shut‐Downprobed by in situ WAXS and SAXS

We have uncovered the detailed degradation mechanism of highly active skeleton-PtCo nanoparticles (NPs) during the potential cycling from 0.5 to 1.5 VRHE using complementary in situ small-angle and wide-angle X-ray scattering techniques (SAXS, WAXS). Based on our findings, two main degradation regimes are identified: Cobalt depletion dominates at...

Microwave Depolymerization of Lignin via Dynamic Vapor Flow Reaction System: HCOOH as Pretreatment Solvent or Reforming Solvent Vapor

Different forms of HCOOH in the depolymerization system play an important role in governing the monomeric products from lignin. We reported two strategies for the introduction of HCOOH to enrich the monophenols from kraft lignin by microwave-assisted depolymerization. The reaction of lignin models showed that HCOOH was in favor of the cleavage of C-O...

CO2 Valorization in Deep Eutectic Solvents

The deep eutectic solvent (DES) has emerged in recent years as a valuable medium for converting CO2 into valuable chemicals because of its easy availability, stability, and safety, and its capability to dissolve carbon dioxide. CO2 valorization in DES has evolved rapidly over the past 20 years. As well as being used as solvents for acid/base-promoted...

Exploring Advanced Oxygen Reduction Reaction Electrocatalysts: The Potential of Metal‐Free and Non‐Pyrolyzed Covalent Organic Frameworks

Oxygen reduction reaction (ORR) electrocatalysis is an area of increasing interest for the in-situ production of H2O2 or the development of energy-related devices such as hydrogen fuel cells. Although pyrolyzed catalysts still offer the best performances to date with reference to the organic-based catalysts, metal-free and non-pyrolyzed covalent organic...
