基于生物电化学原理的生物制氢研究进展

清洁能源对于缓解能源环境压力有重要意义,而生物电化学研究在清洁能源领域受到人们重视。生物电化学是以生物体系的研究及其控制和应用为目的,并融合了生物学、电化学和化学等多门学科交叉形成的一门独立的学科,是在分子水平上研究生物体系荷电粒子(可能包括非荷电粒子)运动过程所产生的电化学现象的科学。在能源环境领域,生物电化学研究环境有机污染物化学能回收,如微生物电解池(microbial electrolysis cells,MECs),氢能的回收同时完成污染物的处理。本文介绍了微生物电解池制氢的基本原理、电极材料产氢评价指标;MECs系统不同结构对产氢效能的影响的比较,MECs实际应用中所存在的问题;提出了今后微生物电解池在制氢方面的发展趋势和研究方向及在制氢方面的应用前景。

Advances in biological hydrogen production based on bio-electrochemical principles

Clean energy resources obtained as great relief to the pressure of energy and environment.And bio-electrochemistry as a separate discipline involves the integration of biology, electrochemistry and chemistry etc, aimed at biological systems and the related controls and applications.On the molecular level, bio-electrochemical researches focus on electrochemical phenomena of charged particles (or non-charged particles) movements.In the energy and environment research field, bio-electrochemistry mainly concerns the chemical energy recovery from organic pollutants, for instance, microbial electrolysis cells (MECs) recover hydrogen energy and treat organic pollutants.This paper introduces the basic principles of MECs for hydrogen production, electrode materials, hydrogen production assessment, and effect comparisons of different types of MECs constructions for hydrogen production.The problems MECs confronted in engineering practice research trends and future prospective is proposed, simultaneously.
