“…Peaks at 458.19 eV and 463.98 eV correspond to Ti 2p 3/2 and Ti 2p 1/2 transitions of TiO 2 [39], further affirming TiO 2 's presence. Peaks at 459.31 eV and 465.23 eV align with Ti 2p 3/2 and Ti 2p 1/2 transitions of TiO(OH) 2 [40]. The impact of reductive treatment on Ti 2 O 3 content is notable and depends on the reduction temperature.…”

Hydrogen-treated titanium dioxide (grey TiO2) crystals were synthesized through a temperature-programmed reduction of commercial TiO2 under an H2/Ar mixed gas flow at elevated temperatures ranging from 600 to 800 °C. Analytical techniques, including Raman spectroscopy and x-ray Photoelectron Spectroscopy (XPS), were employed to probe the presence of oxygen vacancies in the grey TiO2 and to track the variation in Ti3+ species concentration as a function of temperature. The reduced samples obtained at different temperatures were used as photocatalysts to oxidize free cyanide ions under UV light illumination. Among these, the photocatalysts reduced at 600 °C demonstrated superior activity, converting 30 ppm of free cyanide to cyanate ions within 120 min. This reaction time represents a significant enhancement in efficiency as compared to untreated TiO2, which necessitated over 240 min to accomplish the same conversion. The improved performance of grey TiO2 is ascribed to its elevated photocurrent and the positive shift in the flat band energy, which together accelerate electron transfer and limit electron–hole recombination rates.

“…Under such a situation, mixing a second material into the original one to construct the binary composition is an effective means to prepare good catalyst carriers. Yang et al [ 150 ] prepared a series of Pt/SiO 2 -TiO(OH) 2 catalysts with different Pt loading via the solvothermal method using SiO 2 -TiO(OH) 2 binary compositions as carriers. The dehydrogenation experiment results of 12-NEC showed that the catalytic performance of 2.5 wt% Pt/SiO 2 -TiO(OH) 2 was better than that of both the 2.5 wt% Pt/SiO 2 and 2.5 wt% Pt/TiO 2 (OH) 2 catalysts, confirming the effectiveness of the binary carrier.…”

The continuous decline of traditional fossil energy has cast the shadow of an energy crisis on human society. Hydrogen generated from renewable energy sources is considered as a promising energy carrier, which can effectively promote the energy transformation of traditional high-carbon fossil energy to low-carbon clean energy. Hydrogen storage technology plays a key role in realizing the application of hydrogen energy and liquid organic hydrogen carrier technology, with many advantages such as storing hydrogen efficiently and reversibly. High-performance and low-cost catalysts are the key to the large-scale application of liquid organic hydrogen carrier technology. In the past few decades, the catalyst field of organic liquid hydrogen carriers has continued to develop and has achieved some breakthroughs. In this review, we summarized recent significant progress in this field and discussed the optimization strategies of catalyst performance, including the properties of support and active metals, metal–support interaction and the combination and proportion of multi-metals. Moreover, the catalytic mechanism and future development direction were also discussed.
