Boron Phosphide: What’s it all about?

Boron phosphide Is an inorganic compound that is made up of boron phosphorus (BP). It’s a form of semiconductor material. Henri Morvasan (1891) synthesized the material. The sphalerite crystal structure is what it is made of.

Boronphosphide will not react to a boiling alkali or concentrated acid solution. It may, however, react with a molecular base like sodium hydroxide after preheating. Boron-phosphate can withstand oxidation below 1000degC in air and may react with chlorine at approximately 500degC after preheating. At 1100degC vacuum heating causes some phosphorus to be lost, which results in B12p1.8. Its crystal structure is identical to that of the boron caride.

Because it has high resistance to high temperatures and both zinc phosphate’s anticorrosive and high covering and colouring powers, boron white powder is commonly used in non-toxic, anticorrosive paints and coatings. Excellent dispersion, high whiteness and fineness make it a great wear-resistant coating material. Some fields also use boron phosphide as a semiconductor material. However, boron-phosphide has many other uses. Recent scientists tried something new.

Nonmetallic Electrocatalysts For Boron Phosphide

We all know that increased fuel consumption is a major contributor to increasing atmospheric carbon dioxide (CO2) levels, leading to concern about an energy crisis. This problem can be solved by the conversion of carbon dioxide into high value carbon-based fuels, and chemical materials. Electrochemical CO2 removal (CO2RR), however, is a multi-step Electrochemical transfer. These Electrochemical reductions can produce a wide range of products. Methanol, the most valuable C1 product, has an extremely high energy density and is easily stored at atmospheric pressure. This makes it a great fuel-cell material. The University of Electronic Science and Technology of China’s Sun Xoping recently published a boron phosphide-based nanoparticle that is a nonmetallic electrocatalyst for electrochemically reducing CO2 to methanol. At 0.1mKHCO3, the reduction potential was 0.5V. This is a significant improvement over the standard hydrogen electrolyte. The decisive step of the reduced reaction path, *CO+*OH-*CO+*H2O. Therefore, the Gibbs energy for the corresponding Gibbs free electron becomes 1.36 eV. Additionally, the BP (111) crystal surface’s desorption barrier of CO was very high at 0.95 eV. The CH2O and CO2O corresponding Gibbs free energies were 1.36 eV. These factors are important for high selective CO2 reduction to methanol with the BP catalyst.

Applications Prospect

Before this invention, CO2RR catalysts could have been made from precious metals. Metal-based and metal-based metals are often used. But the former were difficult to apply in large quantities due to their high costs, while the latter ran the risk of metal ions releasing into the environment during operation. Professor Sun Xuping and his team made this possible by reducing the costs while increasing the effectiveness of the reaction. The future holds many opportunities for large-scale application.
