近年來,一些實驗室在開發(fā)新催化劑方面取得了很大進(jìn)步,個別實驗室更傾向于采用他們獨(dú)特的催化劑評估策略來報道催化劑性能,如產(chǎn)率,穩(wěn)定性,turn over numbers(單位活性中心上轉(zhuǎn)化了的反應(yīng)物的分子數(shù))和效率等。多數(shù)情況下,對照實驗被忽略或者忽視。對研究者而言,這并不罕見,僅通過單個結(jié)果就得出了非常重要的結(jié)論,在沒有進(jìn)行任何對照實驗或者所有相關(guān)實驗驗證,或者未評估假象的前提下得出了未經(jīng)證實的性能聲明,盡管是無意的,這將會很快成為被批判的目標(biāo)。
基于以上問題和亂象,《ACS Energy Letters》期刊的主編Prashant V. Kamat教授與該期刊的幾位高級編委,共同署名發(fā)表了題為"Why Seeing Is Not Always Believing: Common Pitfalls in Photocatalysis and Electrocatalysis"
的文章,請參閱ACS Energy Lett. 2021, 6, 707?709,向廣大光催化及電催化研究者強(qiáng)烈呼吁“ Validate your results. Employ appropriate scientific methods to verify the outcomes and rule out all other possibilities before announcing an important conclusion”-“請驗證您的結(jié)果。在發(fā)布重要的結(jié)論前,請采用適當(dāng)?shù)目茖W(xué)方法來校驗結(jié)論和排除其他可能性。”
"Seeking answers to the question why or why not the observed phenomenon should occur is an integral part of research.It is important to be your own critic while analyzing the results. Seeing is not always believing. Do not just believe what you see until it is fully vetted and you have obtained solid supporting evidence to justify your conclusion."
