Fe/TiO_2/酸改性土催化剂制备及可见光性能研究

以TiOSO4为钛源,Fe(NO3)3为铁掺杂剂,H2SO4改性煅烧高岭土为载体,采用沉淀法制备Fe/TiO2/酸改性高岭土催化剂,用SEM、XRD、吡啶-IR、UV-vis方法对所制得的催化剂进行表征,并以草酸为目标降解物考察催化剂在可见光下的光催化性能。结果表明:铁的掺杂有利于样品对紫外光强烈吸收并发生红移,而酸改性增加了载体孔道同时也提高了催化剂对可见光的吸收。当铁的掺杂量为2wt%,H2SO4改性浓度为20%时,所制得的催化剂活性最好,草酸降解率高达80%。

Mentoring receipt and personality: Evidence for non-linear relationships

The research investigates the relationship of the Big-Five of personality with mentoring receipt with the use of two independent studies. The findings of the studies show substantial consistency. Equations of quadratic form describe half of the tested relationships better than linear equations. The association of openness to experience and agreeableness with mentoring receipt is of inverted U-shape. The benefits of being open and agreeable for mentoring receipt cease to exist at high values of these traits. On the other hand, emotional stability and conscientiousness demonstrate exclusively positive linear relationships with mentoring receipt. The form of the relationship of extraversion differs between the two studies, but the overall trend is positive. The substantial quadratic component in the association of personality with receipt of mentoring means that research hitherto may be grossly underestimating the effects of personality on developmental relationships because earlier studies assume strictly linear associations. Parts of the results also imply that the associations of certain personality traits with mentoring receipt may depend upon the occupational context.
