Using the principle of discrete-stacking, 3D printing technology is the manufacturing method to produce molded solid parts by layer-by-layer accumulation way based on three-dimensional model. For the rapid proto typing advantage of complex part, it provides the solution for the preparation of cemented carbide parts to a certain extent. After recent years of development, printing technology has played an increasingly important role in the preparation of precision parts.

Hydrogen energy is a renewable clean energy that has been believed to be promising substitute to current energy source of fossil fuels. Electrochemical water splitting is a feasible approach to produce hydrogen gas in which hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) taking place at cathode and anode electrodes respectively.

Nitrogen Oxides are a family of poisonous, highly reactive gases. These gases form when fuel is burned at high temperatures. It is major source is from vehicles, trucks, industry facilities and so on.
