有著界孔洞球珠結構的二氧化鈦光觸媒可以提供比市售P25二氧化鈦更佳的降解能力，原因是它具有較高的比表面積，較佳的光散射性質與極好的傳輸效率。然而二氧化鈦不易吸收可見光且光激發產生的電子電洞對的再結合速率快，此特性限制在光觸媒上的實際應用。因此期望製造具能有效分離電荷的可見光驅動光催化劑。在這項研究中開發了一種新穎有效的光催化劑銀 /複合1T-2H 二硫化鉬 / 二氧化鈦界孔洞球珠。首先使用溶膠 - 凝膠法合成二氧化鈦界孔洞球珠，然後進行微波輔助水熱法。另一方面，使用傳統水熱法合成了複合1T-2H二硫化鉬微米花。接著通過混合硝酸銀，二氧化鈦界孔洞球珠和二硫化鉬微米花，然後通過添加硼清氫化鈉進行化學還原法製備銀 /複合1T-2H 二硫化鉬 / 二氧化鈦界孔洞球珠。具有不同重量百分比的銀，二硫化鉬和二氧化鈦界孔洞球珠比例的光催化劑被合成與調查。我們使用XRD，XPS，拉曼，SEM，TEM，EDS，UV-Vis和PL檢驗合成的樣品。在235 W 氙燈下使用亞甲基藍溶液的降解來測量不同光催化劑的光催化性能。經測試發現在二氧化鈦介孔球珠光催化劑中添加銀和二硫化鉬可使光降解能力提高。這是由於可見光吸收的增強和有效的電荷分離。此外，含有1 wt. %銀和1：2的MoS2：TiO2在所有樣品中表現出最佳的光催化降解能力。

TiO2 photocatalyst having a mesoporous bead-like structure would provide better photodegradation ability than the commercial TiO2 P25 nanoparticles due to its higher surface area, better light scattering, and excellent transport rate. However, the inactivity of TiO2 under visible light and the high recombination rate of photogenerated electron-hole pairs limit its practical applications as a photocatalyst. Thus, it is desirable to fabricate a visible light driven photocatalyst with efficient charge separation. In this study, a novel and efficient photocatalyst Ag/hybridized 1T-2H MoS2/TiO2 mesoporous beads was developed. TiO2 mesoporous beads were first synthesized through sol-gel process, followed by microwave-assisted hydrothermal method. On the other hand, hybridized 1T-2H MoS2 microflowers were synthesized through conventional hydrothermal method. After, Ag/hybridized 1T-2H MoS2/TiO2 mesoporous beads were fabricated by mixing AgNO3, TiO2 mesoporous beads, and MoS2 microflowers, followed by chemical reduction method via addition of NaBH4. Photocatalysts having different weight percentages and ratios of Ag, MoS2, and TiO2 mesoporous beads were synthesized and investigated. The synthesized samples were characterized using XRD, XPS, Raman, SEM, TEM, EDS, UV-Vis, and PL. The photocatalytic performance was measured through the degradation of methylene blue solution in the presence of different photocatalyst samples under a 235 W Xe lamp. It was found out that the photodegradation ability was greatly enhanced by the addition of Ag and MoS2 to TiO2 mesoporous beads photocatalyst. This was due to the enhancement of the visible light absorption and the efficient charge separation. Furthermore, the photocatalyst containing 1 wt. % of Ag and 1:2 ratio of MoS2:TiO2 exhibited the highest photodegradation ability among all samples.
