Catalyst carriers yɛ nneɛma atitiriw a ɛho hia wɔ nnuru a ɛyɛ adwuma mu. Wɔn dwumadie titire ne sɛ ɛbɛma mmoa, apete ne stabilization ama active components, ɛnam so ama catalytic efficiency atu mpɔn na atrɛw ɔsom nkwa a ɛwɔ catalysts mu. Esiane sɛ nnwuma te sɛ nnuru, nneɛma a atwa yɛn ho ahyia ho banbɔ, ne ahoɔden renya nkɔso ntɛmntɛm nti, nneɛma a wɔde fa nneɛma a ɛma nneɛma yɛ kɛse no ho ahiasɛm kɔ so yɛ kɛse, na nneɛma a wɔpaw no nso nya adwumayɛ ne sikasɛm so nkɛntɛnso tẽẽ. Mprempren, nneɛma atitiriw a ɛma nneɛma a ɛma nneɛma yɛ kɛse a ɛwɔ gua so no ka dade oxides, carbon a wɔayɛ no adwuma, molecule sieves, ne nneɛma foforo a wɔabom ayɛ ho titiriw.
Metal oxides yɛ nneɛma a wɔde di dwuma kɛse no mu biako, na nea ɛtaa ba no bi ne alumina (Al2O4), silica (SIO2), titanium dioxide (TiO2) ne zirconium oxide (ZRO2). Wɔn mu no, alumina abɛyɛ ade a wɔpɛ wɔ petrochemical field no mu esiane ne soro pɔtee a ɛkorɔn, ɔhyew a ɛyɛ den yiye ne nnuru a ɛnyɛ adwuma nti.

Titanium dioxide ne zirconium oxide wɔ adwumayɛ a ɛkyɛn so wɔ photocatalysis ne nneɛma a ɛkorɔn-temperature catalysis mu, titiriw wɔ owia ahoɔden a wɔsakra ne kar mu mframa a wɔtwe fi mu no mu. Wɔwɔ tumi kɛse.
Activated carbon yɛ porous carbon ade a ɛkorɔn koraa wɔ soro ne adsorption tumi, na wɔtaa de di dwuma ma gas adsorption ne nsu{0}}phase catalytic reactions. Ne tumi a ɛyɛ foforo ne ne bo a ɛba fam no ma ɛyɛ nea nkurɔfo ani gye ho wɔ nneɛma a atwa yɛn ho ahyia ho banbɔ ne nsu a wɔde yɛ adwuma mu.
