据物理学家组织网近日报道,英国萨里大学科学家在较新一期《应用催化学B:环境》杂志发表论文称,他们研发出一种高性价比的超级催化剂,可同时回收导致全球气候变暖的两大温室气体——甲烷和二氧化碳,有望取代现有碳捕获技术,为抑制全球碳排放带来实际效果。
较近在德国波恩召开的联合国气候变化会议上,“全球碳计划”发布研究报告称,化石燃料与工业生产导致的二氧化碳排放打破过去3年零增长局面,2017年出现回升,预计将比2016年增加两倍。专家们认为,全球能源模式从化石燃料转移到低碳或零排放清洁能源,速度太慢,避免本世纪末全球气温升幅达到2℃已经非常困难,而实现1.5℃升幅的目标更是遥不可及。
现有碳捕获技术虽然可以普及,但成本太过高昂,且大多数技术要求满足各种极端条件,才能保证成功。萨里大学科学家汤姆斯·瑞纳和同事,通过向功能强大的镍基催化剂加入锡和二氧化铈,获得一种新的超级催化剂,可将二氧化碳和甲烷转变成一种人工天然气,用作生产燃料和各种化学产品的原材料。
瑞纳表示,气候科学家一直追寻的目标,就是找到方法逆转有害气体对大气的伤害,而新型超级催化剂,不仅能去除这些有害气体,更能一次性将它们转变成再生燃料,可谓一举两得。“这样回收二氧化碳,是一种可替代传统碳捕获技术的可行性选择,将对地球健康带来实际效果。”瑞纳团队已经申请了专利,并在寻求合作伙伴,期望尽快利用这一技术创造改变世界的巨大价值。
According to a recent report by the Physicist Organization Network, scientists from the University of Surrey in the United Kingdom published a paper in the newer issue of "Applied Catalysis B: Environment", saying that they have developed a cost-effective super catalyst that can simultaneously recycle and cause global climate change. Two of the hottest greenhouse gases, methane and carbon dioxide, are expected to replace existing carbon capture technologies and have a practical effect on curbing global carbon emissions.
Recently, at the United Nations Climate Change Conference held in Bonn, Germany, the "Global Carbon Project" released a research report saying that carbon dioxide emissions caused by fossil fuels and industrial production broke the zero-growth situation in the past three years, and rebounded in 2017, and is expected to increase compared with 2016. double. Experts believe that the shift of the global energy model from fossil fuels to low-carbon or zero-emission clean energy is too slow. It is very difficult to avoid a global temperature rise of 2°C by the end of this century, and the goal of achieving a 1.5°C rise is even more out of reach.
Existing carbon capture technologies, while ubiquitous, are prohibitively expensive, and most require a variety of extreme conditions to be successful. By adding tin and ceria to a powerful nickel-based catalyst, University of Surrey scientist Thomas Reiner and colleagues have obtained a new supercatalyst that converts carbon dioxide and methane into an artificial natural gas that can be used as a fuel for production and raw materials for various chemical products.
Rena said that the goal of climate scientists has been to find a way to reverse the damage of harmful gases to the atmosphere, and the new super catalyst can not only remove these harmful gases, but also convert them into renewable fuels at one time, which can be said to kill two birds with one stone. "Recovering carbon dioxide in this way is a feasible alternative to traditional carbon capture technology, which will bring practical effects to the health of the earth." The Rena team has applied for a patent and is looking for partners, hoping to use this technology as soon as possible to create Great value to change the world.
