金催化領(lǐng)域的幾位專家
|
||||
|
納米金催化的發(fā)展不過短短20年,卻取得了非常引人注目的成果。隨著對金催化劑的深入研究,很多新興的反應(yīng)也在逐漸開展起來。這里向大家介紹我所知道的幾位國內(nèi)外知名的學(xué)者,也歡迎大家補充。 1,Masatake Haruta (春田正毅)。他可以說是金催化的創(chuàng)始人,1982年就開始制備金催化劑,1989年發(fā)表在Journal of Catalysis上的有關(guān)CO低溫氧化的文章(J. Catal. 115 (1989) 301)引起轟動,因為在此之前,對金的潛在催化性能只是做一些理論上的推斷,而沒有實際的應(yīng)用。這篇文章一出,引發(fā)了金催化劑的研究熱潮,以后每年在金催化劑上做CO氧化的人不計其數(shù),文章都發(fā)爛了。所有的文章都會引用到上面提到的那篇JC。后來1998年Haruta教授又在JC上發(fā)表了一篇文章(J. Catal., 178 (1998) 566),講的是丙烯環(huán)氧化反應(yīng)的,從此做丙烯環(huán)氧化的人又多了起來,呵呵。我曾和Haruta教授合作過,他是個很nice的人。有一次聊天時他說1989年CO氧化,過了10年(1998年)丙烯環(huán)氧化,所以他希望2007年(又是10年)再出現(xiàn)一個突破。2006年Haruta教授離開國立研究所到一個私立大學(xué)當(dāng)教授,衷心希望他的愿望能夠?qū)崿F(xiàn)。 2,Graham Hutchings。JC的副主編,也是金催化劑的創(chuàng)始人之一。這里說起來有點意思,1982年他也開始做金催化劑,但是由于當(dāng)時是一個公司的項目,研究成果不允許發(fā)表文章,所以一直到1985年才報道。他一直集中研究金催化劑上的選擇性氧化,尤其是2005,2006年接連在Science,Nature上發(fā)表了2篇文章,牛的很:)。 3, David W Goodman,大牛人一個。他主要是利用表面科學(xué)做金催化劑表征工作的,發(fā)表的文章檔次很高,Science上好幾篇,隨便來一篇就是JACS之類的。 4,Avelino Corma,也是牛人。做CO氧化和液相選擇性氧化,發(fā)的文章也很多,檔次也很高。 5,牟中原,臺灣的。近年來在金催化劑上做的很好。 6,徐柏慶,清華大學(xué)教授。做金催化劑上CO氧化,也做的很好。 以上只是介紹了幾個我知道的,難免漏掉很多,歡迎大家補充。有關(guān)的文章我想大家都會查到。Applied Catalysis A: General 2005年 291期就是專門講金催化的,有興趣的話可以去看看。 [ Last edited by daiqiguang on 2007-5-8 at 16:19 ] |

做金催化的人很多,但是做得好的人卻不多。很多文章就是炒作,缺乏科研 應(yīng)該有的深度。缺乏原創(chuàng)性。 很多文章看起來很“廉價”,沒有多少數(shù)據(jù),兩個星期也能出篇文章。 好比說有些人這篇文章把黃金放在這個載體上,那篇文章把黃金放在另外一個 載體上,換一個載體出一篇文章。 更有甚者,同樣的載體,只是合成條件略有不同,竟然同時出了三五篇文章, 而且也不互相引用,沒有指出自己已經(jīng)把類似文章投給其他地方了。 還有的文章,中心思想是他合成出了納米載體,結(jié)論是納米比不納米的好, 這種結(jié)論,即使不做實驗也知道。 還有的文章,轉(zhuǎn)化率不高。根據(jù)Haruta的結(jié)果,Au/TiO2在室溫下就能100% 氧化一氧化碳,但是有部份人合成了新型Au/TiO2催化劑,發(fā)現(xiàn)在300度才能 100%氧化一氧化碳。他們寫文章規(guī)避了Au/TiO2在室溫下應(yīng)該能100%氧化 一氧化碳的文獻事實,或者王顧左右而言它說實驗條件不一樣,“后續(xù)研究 正在進行中,有待將來報道”(雖然過了幾年都不見報道),或者號稱自己 的比活性最高,那種指標對自己有利就選那種指標(比活性,或者T50)。 千呼萬喚始出來的好文章、嚴肅認真的、有深度的好文章太少了! 推薦以下好文章: [1] F. Moreau, G.C. Bond Applied Catalysis A 302 (2006) 110. Gold on titania catalysts, influence of some physicochemical parameters on the activity and stability for the oxidation of carbon monoxide [2] Wolf, A., Schüth, F. Applied Catalysis A 226 (2002) 1. A systematic study of the synthesis conditions for the preparation of highly active gold catalysts 象這種擲地有聲、一言九鼎、系統(tǒng)詳細、他報道了以后別人就沒有必要再去 反復(fù)重復(fù)報道(因為結(jié)論已經(jīng)很確鑿)的好文章真是值得一讀。 [ Last edited by zhenmafudan on 2007-3-9 at 05:14 ] |
