Among various sustainable energy sources, solar energy is considered promising due to its inexhaustible, universal, large capacity, and environmentally friendly advantages. Solar energy can be used by photothermal, photovoltaic and photocatalytic methods, including solar energy to fuel conversion, solar water splitting, solar photovoltaic, artificial photosynthesis and photocatalytic chemical synthesis, etc., so that solar energy can be applied in many fields.
Catalysts play an important role in all processes of solar energy conversion. Alfa Chemistry Catalysts provides customers with a wide range of catalysts for solar energy, so as to meet the huge challenge of effectively using solar energy in a clean, economical and convenient way.
Catalysts for Converting Solar Energy into Chemical Energy
Catalyst for Photothermal Catalysis
Photocatalysts for Air Purification
- Purify various pollutants through photocatalytic oxidation (PCO), such as volatile organic compounds (VOC) or inorganic gases (NOx, SOx, CO, H2S, ozone, etc.) at relatively low concentrations. Photocatalysis has used a variety of materials as catalysts. For example, metal oxides include binary compounds (TiO2, ZnO, WO3, Fe2O3, ZrO2, etc.), ternary compounds (vanadate, tantalate, tungstate and bismuthate, etc.) and other complex oxyhalides.
