Controllable synthesis and photocatalytic activities of rod-shaped mesoporous titanosilicate composites with varied aspect ratios

Rod-shaped mesoporous titanosilicate composites (RMTSs) with controllable aspect ratios (ARs) were fabricated using cetyltrimethylammonium bromide (CTAB) and ammonium hydroxide (NH4OH) at a continuous stirring rate, resulting in ARs ranging from 1 to 5. Slowing the stirring rate or increasing the concentration of CTAB mainly impacted the length growth, whereas NH4OH affected the width growth. Photocatalytic activity studies revealed that the length of RMTSs played a more significant role than the width at lower ARs in their photocatalytic activity.

RMTSs with controllable ARs were fabricated using NH4OH as a catalyst and CTAB as a template under stirring. The length of RMTSs played a more significant role than the width in their photocatalytic activity.Figure optionsDownload as PowerPoint slide
