英文摘要：

Taking sieve sorbent SBA-15 as a carrier, the composite of Ni（OH）2/SBA-15 sieve sorbent was prepared with simple chemical precipitation method and its material phases and superior performance of capacitance were investigated by means of X-ray diffraction, SEM, TEM, and electrochemical working station. The result showed that the uniformity of sulphuric-acid modified sieve sorbent SBA-15 was higher than that of pure one. Remarkable change of porosity took place with the former and its specific surface area increased. The surface morphology of Ni（OH）2/SBA-15 composite was of nanometer-sized cellular structure. Active material of Ni（OH）2 was composed of a-Ni（OH）2 with layered structure. It was shown by electrochemical performance test that the specific capacitance of this composite decreased with the increase of the density of discharging current and the mass-fraction of sieve sorbent SBA-15 in the composite. The sulphutic-acid modified sieve sorbent composite exhibited a better superior performance of capacitance and dynamic performance than the pure sieve sorbent composite, the maximum specific capacitance of the former being 1 069 F/g.
