Ultrafast Synthesis of a Non‐Noble FeCoNiCrZn Multi‐Element Alloy Electrocatalyst for Alkaline Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A nanoporous carbon‐coated FeCoNiCrZn multi‐element alloy on carbon cloth (FeCoNiCrZn‐C@CC) is fabricated by ultrafast pulsed laser irradiation. It has excellent OER performance, achieving an overpotential of only 233 mV at 10 mA cm−2 and remarkable stability for 94 h at 250 mA cm−2, which is due to multiple factors.

Denaturation of Water in Alkaline Melts

Chemistry – A European Journal, EarlyView.
Vapor pressure measurements and ab initio molecular‐dynamics simulations reveal that in ultra‐alkaline media with base concentrations up to 70 mol L−1, the activity of water is dramatically reduced by strong bonding interactions. These disrupt traditional hydrogen bonding patterns, alter vapor‐liquid equilibria, and significantly change molecular ...

Cross‐Carboxylation of Methanol and Other Alcohols With CO2 Into Asymmetric Alkyl Methyl Carbonates Over a CeO2 Catalyst

Chemistry – A European Journal, EarlyView.
One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam

Chemie Ingenieur Technik, EarlyView.
This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.
