Boron Phosphide: What’s it all about?
Boron phosphide, also known as BP (boron phosphide), is an inorganic compound that is made up of boron phosphorus. It’s a form of semiconductor material. Henri Morvasan (1891) synthesized the material. The sphalerite crystal structure is what it looks like.
Boronphosphide will not react to a boiling alkali or concentrated acid solution. It may, however, react with a molten basis such as sodium hydroxide if preheated. Boron-phosphate can withstand oxidation at temperatures below 1000°C. It reacts to chlorine at 500°C. At high pressure, at 2500°C the compound is stable. Over 1100°C some of its phosphorus is lost through vacuum heating. The result is 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 accelerating the atmospheric concentration of carbon dioxide (CO2) and raising concern about an energy crisis. This can lead to global warming. This problem can be solved by the conversion of carbon dioxide to 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 the electrochemical conversion of CO2 to methanol. When the reduction potential of methanol was 0.5V, the Faraday Efficiency of methanol product reached 92.0%. The decisive step in the reduction reaction pathway is *CO+*OH, *CO+*H2O and the corresponding Gibbs energy 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.
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 ion emissions causing environmental pollution. The effort of Professor Sun Xuping and his team saved costs while improving the reaction efficiency. The future holds many opportunities for large-scale application.
