基于此，团队 设计了一系列基于 [8+4]结构的晶态三维共价有机框架（3D COFs） 。 通过调控这些3D COFs中的金属活性位点和局域氢转移效应，成功实现了高效光催化乙炔（C2H2）加氢制乙烯（C2H4） 。其中， ...

It probably dates around 1910. These lamps produce and burn acetylene, and were originally used in mines, before they became a more common form of illumination for vehicles and buildings.

Such is the case of acetylene (C 2 H 2), an essential hydrocarbon with a plethora of applications. This highly flammable gas is used for welding, industrial cutting, metal hardening, heat ...

The researchers showed that you can effectively combust even small amounts of acetylene in mixtures with ethylene. Removing acetylene is a crucial process to prevent poisoning of polymerization ...

Oxygen tanks and acetylene (a colorless, flammable gas) tanks were exploding inside the building. Eleven units responded from PCFR, as well as three from St. Johns County. The business is an ...
