▎ 摘　　要

NOVELTY - A structure comprises a substrate comprising an activated adsorbent material, and a metal material deposited on the substrate. USE - Structure e.g. porous metal-coated structure. Uses include but are not limited to catalytic application, filtration application, photovoltaic application, chemisorption application, biotechnology, biomedical application, fuel cell system, semiconductor application, micro-electronics, gas storage application, etc. ADVANTAGE - The porous structure is prepared with high catalytic activity, using the activated adsorbent material having high adsorption site density and adsorption capacity, and large surface area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the structure, which involves providing the activated adsorbent material in a reactor, and performing at least one atomic layer deposition cycle to deposit metal material by introducing a precursor gas (P1) into the reactor to provide a metal material precursor deposited on the surface of the activated adsorbent material, and introducing a precursor gas (P2) into the reactor to provide the structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an atomic layer deposition apparatus. Atomic layer deposition apparatus (900) Closing valve (906) Opening valves (908,909)
