The device, reported in the journal Science, uses a standard parabolic mirror to focus the sun's rays into a reaction chamber where the cerium oxide catalyst breaks down water and carbon dioxide.

这种在《科学》杂志里所报道的装置使用一个标准的抛物柱面镜把阳光搜集进一个反应室。在这个反应室里，铈氧化物催化剂可以分解水和二氧化碳。

Prices have soared: the cost of cerium oxide (often used as a catalyst) has increased sixfold since the start of the year, and is 20 times higher than in 2005.

Moreover, soil containing biochar releases less methane and less nitrous oxide than its untreated counterparts, probably because the charcoal acts as a catalyst for the destruction of these gases.

ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well

One company exploits this phenomenon by making nanoparticles of the compound cerium oxide, which in that form are chemically reactive enough to serve as a catalyst.
