第一个实验证据的太阳能驱动的热电化学过程（STEP）的废水处理与协同热电联产氢提出。氢的热电联产是一种有用的产品，减少了去除苯酚的能量消耗，并增加了持久性有机物的氧化速率（例如苯酚的去除）。集中的太阳能热能提高待处理废水的温度。较高的温度降低了驱动苯酚氧化所需的热力学能量，并改善了维持较高速率的动力学。太阳能热能降低了电解所需的电势，而光伏上可见的阳光产生了驱动电解的电势。(c) 2013电化学学会。
The first experimental evidence of a solar driven thermal electrochemical process (STEP) for wastewater treatment with synergetic co-generation of hydrogen is presented. The co-generation of hydrogen, a useful product, decreases the energy consumption to remove phenol, and increases the oxidation rate of persistent organics (exemplifed by phenol removal). Concentrated solar thermal heat elevates the temperature of the wastewater to be treated. Higher temperature decreases the thermodynamic energy required to drive phenol oxidation, and improves kinetics to sustain higher rates. Solar thermal energy decreases the requisite electrolysis potential, while visible sunlight on a photovoltaic generates this potential to drive the electrolysis. (c) 2013 The Electrochemical Society.
