“…The whole process (as shown in Scheme ) started from the preparation of MIL‐125(Ti) precursor by using a solvothermal method. [ 23 ] The precursor showed a thin and pie‐like morphology with smooth surface and uniform size distribution. Upon calcinating MIL‐125(Ti) for 1 h, TiO 2 with a similar pie‐like morphology was obtained, which was assembled of interconnected ultrasmall (sub‐20 nm) nanoparticles ( Figure b; Figures S4–S6, Supporting Information).…”

“…46 MOF-SCs can inherit some unique properties of the parent MOFs such as the templated morphology, porosity, surface area, and crystallinity, enhancing their photocatalytic activity for improved performance. 47 MOF-derived templates have shown merits and proven to be viable for extending the bandwidth of MOFs for an array of other applications such as electrode materials, 48 photoanodes for dye-sensitized solar cells panels, 49,50 photocatalysis, 7,51,52 and in electrocatalytic and photoelectrocatalytic applications. 53,54 Also, the careful design and synthesis of MOF-derivatives can address some of the posing challenges associated with the high recombination rate of photogenerated charged species, thus eliminating the use of poisonous sacrificial electron donors and expensive noble metal co-catalysts, making them promising candidates for HER.…”

“…It is desired and of high interest that the metal oxide, TiO 2 , formed from the MOF should possess some properties of the parent MOF such as its porosity, morphology, which can improve the overall performance of the MOF-derived metal oxide. 44,45 This work critically studied the dual-functional photocatalytic activity of MOF-derived TiO 2 for the simultaneous degradation of PMG and H 2 evolution. Different phases of TiO 2 were synthesized and doped with N and S precursors for increased catalytic performance and tested on herbicides with carboxylate functionalities such as glyphosate (PMG), glufosinate-ammonium (GF), and 2,4-dichlorophenoxyacetic acid (2,4-D).…”

Consumption of contaminated water can have detrimental effects on the health of every living organism on earth. There is, thus, a need to develop novel materials and technologies to purify water. Water is also a source of hydrogen, a clean renewable fuel that can be generated through the action of a photoactive catalyst and the earth's abundant solar energy. Using photocatalysis, we can purify water by removing organic pollutants through the photodegradation reaction (oxidation) and produce hydrogen (H 2 ) through the hydrogen evolution reaction (reduction). However, we can combine these two reactions in a single process to achieve an efficient photocatalytic system. Herein, we report the dual-functional photocatalysis (DFP) on herbicidecontaminated water using TiO 2 polymorphs derived from the amino-functionalized metal−organic framework (MOF), MIL-125-NH 2 . Heteroatom TiO 2 doping led to the generation of N-and N,S-doped TiO 2 . Of all the pristine and doped TiO 2 phases synthesized, the N,S-doped anatase (NSTA) was the best dualfunctional photocatalyst in degrading glyphosate (PMG) with simultaneous H 2 production at a rate of 660 μmol g −1 h −1 . Nuclear Magnetic Resonance studies indicate the preferential cleaving of PMG's C−N bonds, here referred to as α and β C−N bonds, leading to the formation of glycine, formic acid, and phosphoric acid as the major degradation products. Density functional theory calculations indicate PMG's activation through the carboxy and phosphoric acid groups on the surface of NSTA and through the phosphoric acid group on the surface of TiO 2 -rutile. Our results suggest that the catalytic activity of NSTA can be attributed to the templated impact of the parent MOF, owing to its porosity, redshifting of the band absorption edge toward the visible region, reduced energy bandgap, surface defects, and the presence of oxygen vacancies. The binding mode of PMG to NSTA and its degradation allowed us to test the photodegradation of other herbicides, such as glufosinate ammonium and 2,4dichlorophenoxyacetic acid. Interestingly, our MOF-derived NSTA proved to be active in purifying water when all three herbicides were combined and produced H 2 with a rate of 329 μmol g −1 h −1 simultaneously.
