Precious Metal Catalysts te mizia

Catalytic Activity sang tak nei:Noble metal catalyst hian catalytic activity sang tak a nei a, chemical reaction a tichak hle. Electronic structure leh physical property danglam tak an neih avangin noble metal te hian tha takin an tichhia thei a, chemical bonds an siam thei a, hei hian reaction rates a ti chak hle.

Selectivity tha tak: 1.1.Noble metal catalyst hian selectivity tha tak a nei a, target reaction te chu selective takin a tichak a, side reaction te chu a pumpelh emaw, a ti tlem emaw a ni. Hei hi noble metal catalyst-te surface active site leh regulatory property vang a ni a, chu chuan catalytic reaction-a reaction pathway duh zawng chu thlan bik takin a pe thei a ni.

Stability sang tak nei:Noble metal catalyst te hian stability sang tak an nei a, hun rei tak chhung catalytic activity an vawng reng thin. Noble metals hian corrosion resistance leh oxidation resistance tha tak an nei a, boruak khirh takah pawh catalytic performance an vawng reng a ni.

Toxicity hniam tak: 1.1.Noble metal catalyst hian toxicity a nei tlem tlangpui a, hei vang hian catalyst dang nena khaikhin chuan boruak tichhe lo zawk an ni. Noble metals-a inherent low toxicity leh biocompatibility avang hian hmanna tam takah pawm a ni nasa hle.
