Noble metal catalyst siam dan tur
Taksa Inbuatsaihna Dan
Physical preparation methods tih hian thil hlu tak takte chu physical means hmanga catalyst-a chantir dan a kawk a ni. Heng hmanrua te hi a tlangpuiin:
Powder hmanga thil siam chhuah (Powder Metallurgy) a ni
Powder metallurgy hi thil hlu tak tak elemental powder dang nena chawhpawlh a, chutah chuan physical method, high temperature leh high pressure te hmanga catalyst siam dan a ni. Hetiang method hian active leh stable tak tak, precious metal catalyst a siam thei a ni.
A chhuahna tur hmun (Evaporation).
Evaporation hi catalyst siam dan a ni a, chu chu metal hlu tak takte chu evaporate-in substrate-ah dahin a ni. Hetiang method hian active leh stable tak tak, precious metal catalyst a siam thei a ni.
A rilru a buai em em a
Sputtering hi substrate-a metal hlu tak tak physically sputtering hmanga catalyst siam dan a ni. Hetiang method hian active leh stable tak tak, precious metal catalyst a siam thei a ni.
Chemical siam chhuahna (Chemical Synthesis) a ni
Chemical synthesis tih hian chemical reaction hmanga metal compound hlu tak tak atanga catalyst siam chhuahna a kawk a ni. Hetiang method hian active leh stable tak tak, precious metal catalyst a siam thei a ni. Physical preparation method nena khaikhin chuan chemical synthesis method hian a thatna a nei a, chu chu preparation process awlsam zawk leh efficiency sang zawk a ni. Mahse, chemical synthesis hmanga siam catalyst te hian activity an nei tlem zawk a, stability pawh an nei tha lo zawk. Chuvangin, physical preparation methods hi highly active leh stable noble metal catalysts siamna atana hmanraw tangkai tak a la ni reng a ni.
A tawi zawngin, noble metal catalyst siam danah hian physical preparation method leh chemical synthesis method te a tel ber a ni. Physical preparation methods hian noble metal catalyst active leh stable tak tak a siam thei a, mahse an preparation efficiency erawh a hniam hle a; chemical synthesis method hmang hian noble metal catalyst active leh stable tak tak a siam thei bawk a, mahse an siam thatna erawh a sang hle thung. Chuvangin, thil awmdan bik atanga siam dan tur dik thlan hi noble metal catalyst siamna atan a pawimawh hle.
