The introduction of oxofluoride anion into anionic group assists to tune optical properties owing to the change of coordination, electronegativity, and according anionic framework. Here, we proposed a rational design of new compounds by fluorine-driven structure and optical property evolution. A new borophosphate Ba 2 BP 3 O 11 with the monoclinic space group P2 1 /c has been synthesized in the sealed system. Ba 2 BP 3 O 11 exhibits a rare P-O-P bridge formation, which is the first example in alkaline-earth metal borophosphates. By further substituting [BO 4 ] 3− with [BO 3 F] 4− , the first alkaline-earth metal/lead fluoroborophosphates M 2 BP 2 O 8 F (M = Ba and Pb) with the same space group were designed. Since the scissors effect of fluorine, in M 2 BP 2 O 8 F (M = Ba and Pb), a BO 3 F tetrahedron corner-sharing with three PO 4 tetrahedra forms 1D chains along the b-axial direction, which are filled by MO n (M = Ba/Pb, n = 5, 6, 8) distorted polyhedra. The first principles calculation shows that the borophosphate Ba 2 BP 3 O 11 has a birefringence about 0.013 @1,064 nm, while the fluoroborophosphates M 2 BP 2 O 8 F (M = Ba and Pb) have the values of 0.035 and 0.043 @1,064 nm, respectively. Such an apparent enhancement in birefringence is derived from synergies of the oxyfluoride and cation. The introduction of fluorine-containing heteroanionic groups provides a feasible strategy to design novel promising optical materials.

The use of polymeric carbon nitride (PCN) for photoredox catalysis is innovating and promoting toward sustainable energy economy. One of the drawbacks of this metal‐free photocatalyst is its insufficient charge separation and transfer. Herein, a metal‐free system was achieved by anchoring PCN on conductive carbon cloth (CCC). CCC in this system facilitated the charge separation and transport of the photoexcitation charges when PCN films were illuminated. Both photoelectrochemical water oxidation and photocatalytic overall water splitting were achieved, and the performances were improved two‐fold with respect to the powder PCN.

Methane, a high‐quality fuel and important chemical raw material, is widely used in industrial production and life applications. However, the utilization and conversion rates of methane are low because methane is a very stable hydrocarbon gas. At present, the main industrial route of methane conversion involves thermocatalysis technology operating at high temperature. However, this approach has the disadvantages of high energy consumption, high equipment requirements, and high reaction temperature, resulting in shortened catalyst lifetime. Therefore, there is an urgent need to develop a new technology that can effectively utilize and transform methane under mild conditions to obtain the target products. As a kind of clean and renewable energy, solar energy has attracted extensive attention, and research on the effective conversion of methane by solar energy has become an important field. Herein, the recent achievements of solar energy in promoting or driving the catalytic conversion of methane are reviewed. The selection and design of photocatalysts used in different photocatalytic methane conversion reactions are focused on, which may provide important guidance for future research on this process. The prospects and challenges of photocatalytic methane conversion are also discussed.
