Platinum palladium precious metal catalyst is a very efficient waste gas treatment catalyst, it is composed of Pt and Pd and other precious metals, so it has very high catalytic activity and selectivity. It can efficiently transform harmful substances in the exhaust gas and turn them into harmless substances, thereby reducing the emission of exhaust gas and protecting the environment and human health on which we depend.
The core components of platinum and palladium catalysts are precious metals such as platinum and palladium, and the choice of these precious metals is very particular, completely depending on the application scenario of the catalyst and the requirements of the catalytic reaction. In general, the mass ratio of platinum and palladium in platinum and palladium catalysts is 1:1 or 2:1, and this ratio can achieve the best catalytic effect. In addition, the support of the platinum palladium catalyst is also very important, which has a profound impact on the performance of the catalyst. Common carriers are aluminum oxide, silicon oxide, yttrium oxide, etc., which provide a stable substrate for the catalyst and ensure a highly efficient catalytic effect.
The common preparation methods of platinum and palladium catalysts include impregnation, co-precipitation, precipitation, physical mixing and so on. The impregnation method is to impregnate a negative carrier (usually an oxide) into a solution containing platinum and palladium ions, and then undergo a series of operations such as drying and reduction, and finally obtain a platinum and palladium catalyst. The coprecipitating method is that the negative carrier and platinum and palladium ions are added to the reaction system together, and the platinum and palladium ions are precipitated together on the surface of the negative carrier to form a platinum and palladium catalyst by controlling the pH value and temperature of the solution. The platinum palladium catalyst obtained by this method has the characteristics of high activity, high selectivity and high stability, which ensures the efficiency and safety of waste gas treatment.
When using platinum and palladium precious metal catalysts, we should pay attention to safety matters. First of all, it is necessary to avoid dangerous situations such as open flame, high temperature and static electricity, which may lead to the deterioration of catalyst performance and even danger. Secondly, the catalyst needs to be checked and replaced regularly to ensure its normal operation and achieve the best catalytic effect.
