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.

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

Chemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

Heteroatom‐Doped Graphdiynes and Their Applications in Photo‐/Electro‐Catalytic CO2 Conversion

Carbon Innovation, EarlyView.
This review highlights the versatile role of doped graphdiyne (GDY) in boosting CO2 conversion, where metal and non‐metal doping simultaneously tune the electronic structure, create abundant active sites, and improve charge separation, light harvesting, and CO2 adsorption.

Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants

Chemie Ingenieur Technik, EarlyView.
The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...
