Role of Ethylene Diamine Tetraacetate as an Additive in Electrolyte on Intermediate Stabilization in Electrochemical CO2 Reduction.

Although an electrochemical CO2 reduction reaction (ECO2RR) can provide an ideal route to produce CH4, its selectivity is significantly hindered due to kinetically complex steps. To improve CH4 selectivity, this study focuses on microenvironmental engineering using an additive of ethylene diamine tetraacetate (EDTA) in electrolyte. EDTA interacts with the Cu catalyst, altering its electronic structure and promoting CO2 activation, in addition, it forms additional hydrogen bonding with key intermediates of *CO and *CHO leading to their stabilization.

Waste paper-derived porous carbon via microwave-assisted activation for energy storage and water purification.

The reuse of waste papers by conversion into valuable carbon materials has received considerable attention for diverse applications such as energy storage and water purification. However, traditional methods for converting waste papers into materials with suitable properties for specific applications are often complex and ineffective, involving consecutive carbonization and activation steps. Herein, we propose a simple one-step microwave (MW)-assisted synthesis for preparing waste paper-derived porous carbons (WPCs) for energy storage and water purification.

Solar-Driven Syngas Production Using Al-Doped ZnTe Nanorod Photocathodes.

Syngas, traditionally produced from fossil fuels and natural gases at high temperatures and pressures, is an essential precursor for chemicals utilized in industry. Solar-driven syngas production can provide an ideal pathway for reducing energy consumption through simultaneous photoelectrochemical CO and water reduction at ambient temperatures and pressures. This study performs photoelectrochemical syngas production using highly developed Al-doped ZnTe nanorod photocathodes (Al:ZnTe), prepared via an all-solution process.
