“…In fact, the global CO 2 concentration has climbed up from 415.78 ppm on January 1, 2021, to 417.73 ppm on January 1, 2022 4 . It is thus anticipated that sustainability issues are still the major concerns following the environmental crisis, thus, continuous research has been carried out to minimize the environmental threats attributed to the burning of nonrenewable fossil fuels 5,6 . Despite the gradual depletion of fossil fuel reserves that contributes to ~85% of the global energy production, the release of toxic and non‐ecofriendly effluents urges the transformation of nonrenewable fossil fuels to renewable fuels 7 …”

The gradual depletion of fossil fuel reserves that contribute to $85% of global energy production and release of toxic effluents urges the transformation toward renewable fuels. Thus, the sustainable utilization of sunlight for water splitting and CO 2 reduction with heterogeneous photocatalysts has come to light. As a semiconductor photocatalyst, ZnIn 2 S 4 has hit the limelight owing to its narrow bandgap and visible-light-responsive properties. However, the limitations of ZnIn 2 S 4 include limited active sites, fast charge-carrier recombination, and low photoconversion efficiency. Beginning from the fundamental photocatalytic mechanism, this review then provides in-depth insights into several modification strategies of ZnIn 2 S 4 , extending from defect engineering, facet engineering, cocatalyst loading to junction engineering, enabling the synergistic construction of high-performance ZnIn 2 S 4 -based systems. Subsequently, the structure-performance relation of ZnIn 2 S 4 -based photocatalysts for hydrogen evolution (HER), overall water splitting (OWS), and CO 2 reduction applications in the last 4 years will be discussed and concluded by the future perspectives of this frontier.

“…The overall rate of energy demand is anticipated to increase by 50% from 2021 to 2050, which is mainly attributed to the rapid increase in the population worldwide and industrialization. [1][2][3] As a result, there is an urgent need to find renewable and clean new energy sources to substitute fossil fuels. Among a plethora of sustainable energy technologies, artificial photosynthesis is a green process of transforming solar energy, which is one of the most abundant resources available on the Earth, into useful chemical energy or fuels.…”

Green energy generation is an indispensable task to concurrently resolve fossil fuel depletion and environmental issues to align with the global goals of achieving carbon neutrality. Photocatalysis, a process that transforms solar energy into clean fuels through a photocatalyst, represents a felicitous direction toward sustainability. Eco-rich metal-free graphitic carbon nitride (g-C 3 N 4 ) is profiled as an attractive photocatalyst due to its fascinating properties, including excellent chemical and thermal stability, moderate band gap, visible light-active nature, and ease of fabrication. Nonetheless, the shortcomings of g-C 3 N 4 include fast charge recombination and limited surface-active sites, which adversely affect photocatalytic reactions. Among the modification strategies, point-to-face contact engineering of 2D g-C 3 N 4 with 0D nanomaterials represents an innovative and promising synergy owing to several intriguing attributes such as the high specific surface area, short effective charge-transfer pathways, and quantum confinement effects. This review introduces recent advances achieved in experimental and computational studies on the interfacial design of 0D nanostructures on 2D g-C 3 N 4 in the construction of point-to-face heterojunction interfaces. Notably, 0D materials such as metals, metal oxides, metal sulfides, metal selenides, metal phosphides, and nonmetals on g-C 3 N 4 with different charge-transfer mechanisms are systematically discussed along with controllable synthesis strategies. The applications of 0D/2D g-C 3 N 4 -based photocatalysts are focused on

We have synthesized a cocondensed bipyridine-ethane periodic mesoporous organosilica (BPy-Et-PMO) as a host material to simultaneously anchor lanthanide complexes and a V-complex in order to develop a heterogeneous catalyst that is at the same time an optical temperature sensor. We focused on the oxidative desulfurization reaction, and for this purpose, BPy-Et-PMO is post-treated with the vanadium oxodiperoxo complex [KVO(O 2 ) 2 ]. After grafting KVO(O 2 ) 2 -BPy-Et-PMO with lanthanide ions (Tb 3+ and Sm 3+ ), the KVO(O 2 ) 2 -Tb,Sm(acac)-BPy-Et-PMO material shows simultaneous catalytic and thermometric performances, but the catalytic activity is significantly reduced. We then developed a hollow BPy-Et-PMO (HBPy-Et-PMO), in which we grew NaYF 4 :Er,Yb inside the hollow PMO cavity (creating a "nanorattle"), while additionally grafting the hollow PMO walls with the vanadium oxodiperoxo complex. This hollow PMO system is a heterogeneous catalyst that shows no loss in catalytic activity while at the same time being a temperature sensor operating in a temperature range relevant for the selected catalytic reaction. Therefore, the nanorattle KVO(O 2 ) 2 -HBPy-Et-PMO@NaYF 4 :Er,Yb particles prove to be an excellent multifunctional new material for both catalysis and thermometry measurements.
