Abstract. The composites with nanosized gold loaded in nanoporous ceria were prepared on a large scale by a facial and environment-benign sol–gel process. These materials were characterized by XRD, ICP, BET, UV–vis absorption, XPS, HRTEM and EDX. The main factors such as size and surface state of the Au and defect in the ceria could be adjusted by acid treatment of the composites in asc…
Abstract: A kind of activated carbon with further carbon dioxide and potassium hydroxide activations for hydrogen storage was investigated. The carbon dioxide and potassium hydroxide activations have apparently different effects on the pore structures and textures of the activated carbon which closely associated with the hydrogen storage properties. The potassium hydroxide activation can r…
