Synthesis, Characterization and Catalytic Application of Mesoporous Metal Oxides (Alumina, Nickel Oxide and Others);

Study of Preparation and Adsorption Properties of Mesoporous Carbons via Sol-Gel Method;

Assembly of mesoporous NiO microspheres based on sheet-like precursors

In order to prepare the high surface area activated mesocarbon microbeads with high mesopore content, mesophase pitch microbeads were activated with KOH at 850 ℃ and the effects of the weight ratio of KOH/MMB to the structure and morphology of activated carbon microbeads were investigated in this paper.

The preparation of activated carbon with mesopore by catalyst was summarized.

Nano-SiO_2 with high activity and mesopores was prepared through sol-gel synthesis followed bylow-temperature heat treatment and ball milling firstly in our experiments.

In this paper,the development of mesopores activated carbon (AC) at home and abroad is reviewed.

The paper reviewed the advance in the researching of the mesopores activated fibers at home and abrodad,related how to improve its mesopores content in two respects of the modification of the activation agent and material modification,and put forward the researching tenders in the future.

This paper discusses the technological condition which affects the characteristics of the activated carbon with developed middle hole made from Datong Zuoyun coal,such as carbonization temperature,carbonization speed,activation temperature,activation time,size,H 2O/C.

Based on prototype observation method, the vibration of middle hole and arch dam are observed when releasing flood under different operating modes, and the right wall of spillway is observed when releasing flood by spillway in Dongfeng hydropower station, and the observed results and the dam operation are analyzed.

Due to its narrow valley, high dam and big discharge, on the basis of many alternatives comparison and selection at different design stages, we decide to use 5 crest overflow surface holes for energy dissipation, 6 middle holes in the dam body, one spillway tunnel at left bank, plunge pool and plunge pool dam behind the dam, 2 escape bottom holes in the dam body.
