Table of Contents
有期刊名,有印尼籍博士後的全名,所以很好找。
難得(?)npg有直接開放全文權限,所以有興趣的可以直接上去看。

"CuMnOS Nanoflowers with Different Cu+/Cu2+ Ratios for the CO2-to-CH3OH and
the CH3OH-to-H2 Redox Reactions"
Discussion中有詳述反應式與ΔG,應該是這篇研究的重點;
小弟不才,不是材料專科,所以看得很吃力,還望材料前輩不吝指教。
不過在最後一段開頭,作者直接講明了:
"In summary, we demonstrate the nanoflower-like CuMnOS catalyst system to
complete the conservative CO2-CH3OH hydrogenation-dehydrogenation cycle in an
aqueous solution at normal temperature and pressure without additional energy
inputs and reagents."
因此,「不耗能」的說法或許不夠準確,
但的確是「在室溫正常壓力下不需額外加入能量」即可完成此催化反應。
而催化的關鍵應該是在於晶格對氧鍵結的弱化。
(The bond weakening concept in forming the active lattice oxygen opens a
route to increase the catalytic activity of inorganic catalysts for redox
reactions at mild condition.)
另外,根據反應式似乎的確沒有特別難搞的副產物。
這是小弟的理解,如有謬誤還望各界先進指教。
如果這催化劑與反應是可行的,接下來就是解決效率和產量問題,
也許就能邁向商業量產了。

好久沒這時間看paper了,頭好痛...
