采用绿色低温水热合成法合成了一种新型的掺镍锆酸锶钙钛矿沼气重整催化剂。该催化剂已被证明在相对较低的温度下对富甲烷沼气的转化非常有效，对合成气的形成具有很高的选择性，并且在富碳反应混合物中具有极好的抗碳沉积能力。催化剂表现出非常低的碳沉积，不随时间增加，因此表现出优异的稳定性。使用由低温热液途径产生的催化剂，为从沼气中提取有用的化学物质提供了一个潜在的非常有吸引力和可持续的来源，否则这些化学物质可能会被浪费和有害地排放到大气中。
A novel nickel-doped strontium zirconate perovskite catalyst for biogas reforming has been synthesised using a green, low temperature hydrothermal synthesis. The catalyst has been shown to be very efficient towards the conversion of methane-rich biogas at relatively low temperatures with high selectivity towards synthesis gas formation and extremely good resistance to carbon deposition in carbon-rich reaction mixtures. The catalyst displays very low carbon deposition which does not increase over time, and as a result shows excellent stability. The use of a catalyst produced by a low temperature hydrothermal route provides a potentially very attractive and sustainable source of useful chemicals from biogas that otherwise might be vented wastefully and detrimentally into the atmosphere.
