我国氢能产业发展和氢资源探讨

分析了我国氢能产业近期发展情况,我国氢能产业正步入快速发展机遇期。指出氢能是21世纪最具发展潜力的一种清洁二次能源,具有"清洁、高效、安全、可持续"四大特点,被誉为未来世界能源架构的核心。重点讨论了我国氢资源和绿色氢气制备问题,指出目前实际使用的氢气包括"灰氢""蓝氢"和"绿氢"三大类,显然"灰氢"不可取,"蓝氢"可以用,"废氢"可回收,"绿氢"是方向。讨论了加快氢能系统建设,建立发展氢气存储和运输系统及加氢站基础设施建设等问题。未来,我国氢能产业发展潜力巨大,但是在下决心大力发展氢能产业时,需要高度注意目前存在的实际情况和困难,要防范一系列的产业风险,做到有序发展,稳中有进,才能实施氢能产业的可持续发展。     

烧碱副产氢的应用

电解制烧碱副产氢在国外的研究热点在于金属氢化物储氢和氢与燃料电池的结合。国内氢的利用率很低，除少量作还原剂外大部分用于合成盐酸或只用其热焓，且有３０％以上放空，基于此，提出寻找如己内酰胺、苯胺、甲醇等的加氢产品和作为燃料的开发使用等办法以提高氢的利用率。

Local Structure of Defects on Hydrogen- and Vacuum-Reduced TiO2 Surfaces

A comparative study was performed on two TiO₂ (110) surfaces: one annealed in vacuum, the other annealed in hydrogen. Local geometric and electronic structures were characterized using scanning tunneling microscopy and spectroscopy, in conjunction with conventional surface analytical techniques. Each surface exhibited a distinct pattern of electronic and geometric inhomogeneity. The origin of the defect structure resulting from the two treatments is discussed in terms of reduction mechanisms, defect formation thermodynamics, and chemical reactivity. The implication of local variation in the defect structure to the TiO₂ interaction with reactive species is also addressed.     

Biogas Production: New Trends for Alternative Energy Sources in Rural and Urban Zones

Biogas is a biofuel with a high energy value and basically consisting of methane, which can be used as a renewable energy source as a substitute for natural gas or liquefied petroleum gas. It can be produced by anaerobic digestion of agricultural organic waste or manure in rural areas, where it can be used to generate electric, thermal or mechanical energy. It can also be generated in landfills from the organic fraction of municipal solid wastes and used as an alternative energy source in urban areas. Industrialized and urbanized areas are afflicted by serious environmental problems associated with the generation of organic residues. Anaerobic microorganisms can degrade pollutants resulting in two kinds of products, i.e., digested sludge and biogas, which can be exploited as a soil fertilizer and a renewable energy source, respectively. The correct management of residual waste involves high costs, and inadequate treatment and storage can compromise its quality. Environmental agencies have been encouraging the dissemination of anaerobic digesters to produce biogas from organic residues and the use of the resulting sludge as fertilizer since it is able to destroy pathogenic agents and reduce the humidity level. This review aims to evaluate the production capability of biogas and its application as an alternative energy source in rural and urban areas.
