TiO2基光催化在环境污染治理领域的研究进展 英文版
作者：耿启金 著
出版时间： 2016年版
内容简介
The past 40 years have seen the emergence worldwide of a growing desire to take positive actions to restore and protect our environment from the degrading effects of all forms of pollution. Since this pollution is a direct or indirect consequence of waste， the seemingly idealistic demand for zero discharge can be construed as an unrealistic demand for zero waste. However， as long as waste exists， we can only attempt to abate the subsequent pollution by converting it to a less noxious form. In recent years， the international environment community， especially in China， has been increasingly concerned about the stresses imposed on the natural environment by many chemical and energy-generating processes. As a result， the whole world is witnessing an accelerated development and implementation of new green technologies which are called to provide ecologically responsible solutions for the much needed supply of drinking water and clean air.
