摘要:
TiO_(2)納米材料是TiO_(2)經過納米技術處理過的高級金屬氧化物光催化劑,同時也是一種被廣泛研究在水處理中的半導材料,在工業(yè)中的物理研究價值極高。TiO_(2)納米材料是近現(xiàn)代新興起來的一種光催化劑,因為它在化合反應中氧化性強,并且又耐化學腐蝕性,催化活性也相對較高,所以在生活和工業(yè)中常利用光來活化TiO_(2),使其產生氧化還原作用,將光能轉化成電能和化學能,對房屋裝修進行殺菌及處理工業(yè)廢水,較少產生對環(huán)境的污染。還可利用氧化性強的特點來氧化還原它附近附著的物質,進行殺菌和清除污染物。近年來,國家也出臺相應的政策和措施對環(huán)境進行保護,TiO_(2)以其無毒無害性、化學催化穩(wěn)定性高、催化劑的物質形態(tài)可控、光源被催化活性強等優(yōu)點得到了各應用技術行業(yè)的持續(xù)關注。文章主要分析目前關于納米TiO_(2)光催化性能運用原理和特點,以及對提高TiO_(2)納米材料光催化性能的創(chuàng)新研究。

摘要:
基于修飾的高分子網絡凝膠法,通過簡單的工藝流程制備出高效的ZnO/TiO_(2)納米復合光催化劑,并調節(jié)復合物中成分的比例優(yōu)化了光催化劑的性能。研究結果發(fā)現(xiàn),微量的TiO_(2)添加和高濃度TiO_(2)復合均改善了顆粒狀ZnO納米光催化劑的催化活性,它們在模擬太陽光照下對甲基橙的降解效率更高,增強的性能分別歸因于表面氧空位缺陷增多和多元異質結結構增強的界面電荷轉移引起的高光生電子-空穴分離率。此外,ZnO和TiO_(2)對亞甲基藍和甲基橙的光催化降解存在一定的選擇性,這與催化劑表面帶電性和污染物分子的離子性有關。抑制劑實驗表明催化劑表面形成的活性物種羥基自由基、超氧自由基和光生空穴均參與亞甲基藍和甲基橙的降解反應,在甲基橙的降解反應中超氧自由基起主導作用。循環(huán)實驗證實所制備的光催化劑具有較高的穩(wěn)定性。為探索可能的實際應用,進一步研究了催化劑用量和污染物溶液的pH值對催化劑的光催化性能的影響。結果表明,催化劑用量的增加為污染物分子和入射光提供了更多的活性位點,提高了污染物降解效率;因堿性溶液含高濃度強氧化性的羥基自由基,催化劑在堿性環(huán)境中光降解污染物的效率明顯提高。

摘要:
采用TiO_(2)/ITO光電極研究了不同光照方式對有機污染物光電催化降解的影響,通過光強測試解析了有機污染物物降解過程及有機污染物的空穴清除能力。結果表明:與正光照射相比,背光照射光電催化降解苯酚、腐植酸和酸性橙的速率分別提升了16.19%、26.09%和38.87%;正光照射時,光經過溶液導致的光強損失減弱了光陽極表面光照強度,從而降低了催化效率;背光照射對有機污染物降解效率提升的程度與有機污染物吸收光的能力呈正相關關系;由于背光照射避免了光經過溶液造成的光強損失,提高了空穴捕獲能力,相較于沒有污染物的條件產生了更大的光電流。

摘要:
本文利用脈沖激光沉積技術在LaAlO;(001)襯底上生長了單晶銳鈦礦和雙相TiO_(2)薄膜,并利用X射線衍射和透射電子顯微術對薄膜的顯微結構進行了系統(tǒng)表征。單晶銳鈦礦薄膜在LaAlO;(001)襯底上實現(xiàn)了外延生長,雙相TiO_(2)薄膜以單晶銳鈦礦TiO_(2)為基體,在其中夾雜著金紅石TiO_(2)顆粒。TiO_(2)薄膜的相結構可通過調整靶材與襯底的間距來調控,遠靶基距(150 mm)利于單晶銳鈦礦薄膜生長,近靶基距(50 mm)易獲得雙相TiO_(2)薄膜。銳鈦礦TiO_(2)電鏡樣品在離子減薄過程中易發(fā)生表面還原,導致電鏡觀察中出現(xiàn)莫爾條紋。研究表明30%H_(2)O_(2)浸泡可有效去除離子減薄樣品表面的損傷層,防止莫爾條紋的出現(xiàn)。

摘要:
In this work,a covalent organic framework(COF),which is constructed by the building blocks of[5,10,15,20-tetrakis(4-aminophenyl)porphinato]copper(Ⅱ)(CuTAPP)and p-benzaldehyde,is employed to integrate with TiO_(2) for the purpose of establishing a Z-scheme hybrid.Within the system,isonicotinic acid performs the role of a bridge that connects the two components through a coordination bond.Further photocatalytic application reveals the hybrid framework is able to catalyze CO_(2) conversion under simulated solar light,resulting in CO production rate of 50.5 μmol g^(-1)·h^(-1),about 9.9 and 24.5 times that of COF and pristine TiO_(2),respectively.The ameliorated catalytic performance owes much to the por-phyrin block acting as photosensitizer that augments the light absorbance,and the establishment of Z-scheme system between the inorganic and orga nic comp on ents that enhances the separati on of the carriers.In addition,the chemical bridge also ensures a steady usage and stable charge delivery in the catalysis.Our study sheds light on the development of versatile approaches to covalently in corporate COFs with inorga nic semic on ductors.

摘要:
研究了鈦礦渣作水泥混合材時某水泥廠電耗偏高的原因以及鈦礦渣對水泥強度和強度增長率的影響。研究表明,水泥廠鈦礦渣中TiO_(2)含量高達12.76%,導致鈦礦渣活性較低;鈦礦渣易磨性差是水泥廠電耗偏高的主要原因。普通礦渣和鈦礦渣在相同比表面積情況下,鈦礦渣對水泥的早期強度影響不大,對后期強度影響明顯;在不同比表面積情況下,隨著比表面積的增加,普通礦渣和鈦礦渣的活性都會增加,而普通礦渣28d活性增加更加明顯,鈦礦渣28d活性雖然有一定增加,但不明顯。

摘要:
In this work, monolithic functional ceramic membrane was fabricated, and evaluated usingintegrated ozonation and ultrafitration. The initial TiO2/Al2O3composite membrane was prepared byassembling TiO2nanorods, which grew through calcination from rutile TiO2powders, on Al2O3supportlayer. Then the mesoporous Ti-Mn mixed oxide was loaded on the composite membrane by a simplevacuum dip-coating process. According to the images of scanning electron microscope (SEM) andtransmission electron microscopy (TEM), the thickness of Ti-Mn layer was about 100nm, which coateduniformly on the surface of micro particles in the composite membrane. The result of integrated ozonationand ultrafiltration test indicated that catalytic ozonation played a important role in the process and broughtout an enhancement of recovery of the permeate flux and CODCr, color and aniline removal, meanwhile,the influent with CODCrbelow 200 mg/L could be effectively handled to meet the requirement of waterreclamation (CODCr<60 mg/L). Consequently, this kind of monolithic functional membrane with themultifunctions including catalytic ozonation, separation and anti-fouling has potential application in waterproduction and wastewater treatment processes.
