Solar energy-driven sustainable process for synthesis of ethylene glycol from methanol

Direct photocatalytic coupling of methanol to ethylene glycol (EG) is highly attractive. The first metal oxide photocatalyst, tantalum-based semiconductor, is reported for preferential activation of C-H bond within methanol to form hydroxymethyl radical ( CH2OH) and subsequent C-C coupling to EG. The nitrogen doped tantalum oxide (N-Ta2O5) photocatalyst is an environmentally friendly and highly stable candidate for photocatalytic coupling of methanol to EG.

China s expanding influence in UN

Chinas ascendancy in the UN seems almost unquestioned. A study by Gateway House has traced Chinas expanding influence in the world body, its related bodies, and influential non-UN multilateral bodies.The research was conducted over four months .

Tuning the intermediate reaction barriers by a CuPd catalyst for CO2 electroreduction to C2 products

An intimate CuPd(100) interface was designed to lower the energy barriers of intermediate reaction (CO2 hydrogenation and C-C coupling) and improve the efficiency of C2 products. The optimal CuPd(100) interface catalyst exhibited a C2 Faradaic efficiency of 50.3%, which was 2.1 times higher than that of Cu catalyst (23.6%) at -1.4 VRHE in 0.1 M KHCO3
