“…Therefore, the greater the conjugation degree, the higher the shift. Band gap energy of MOF La-PTC based PTCDA ligand is lower than band gap energy of La-MOF based 2,6-naphtalenedicarboxylic that are 2.25 eV and 3.10 eV for La-PTC and La-MOF respectivelly (Zulys et al, 2021;Batubara & Zulys, 2019).…”

The yttrium based metal-organic framework (MOF) Y-PTC was synthesized by the solvothermal method using perylene as the linker and yttrium as metal ion. This study aims to assess the photocatalytic activity of yttrium-perylenetetracarboxylate (Y-PTC) metal-organic framework (MOF) toward methylene blue and methyl orange under visible light irradiation. The results of the FTIR analysis showed that Y-PTC MOF had a different structure and composition from its precursor (Na4PTC). The Y-PTC MOF has a bandgap energy value of 2.20 eV with a surface area of 47.7487 m2/g. The SEM-EDS analysis showed an elemental composition of yttrium, carbon, and oxygen, were 6.9%, 72.1% and 20.7%, respectively. Furthermore, Y-PTC MOF was able to adsorb dyes at the optimum by 78.10% and 35.57% toward methylene blue (MB) and methyl orange (MO) at the dispersion period of 60 mins. Y-PTC MOF exhibited photocatalytic activity towards the degradation of methylene blue and methyl orange under visible light irradiation. The addition of H2O2 inhibited Y-PTC photocatalytic activity towards MO degradation from 50.89% to 26.38%. In contrast to MO, the addition of H2O2 had a positive effect on MB, which increased the degradation from 87.56% to 91.65%. Therefore, Y-PTC MOF possessed the potential of a photocatalyst material in dyes degradation under visible light irradiation.

“…MOF La-PTC was synthesized according to the method in our previous research [9] La(NO 3 ) 3 •6H 2 O powder, Na 4 PTC at a molar ratio of 1.0:0.5 in dimethyl formamide (DMF), and deionized water mixture (1:5 v/v) in a Teflon liner. After the mixture was stirred magnetically at 300 rpm for 60 min, the Teflon liner was sealed in a solvothermal reactor and heated at 170 °C for 24 h. After cooling to room temperature, the product was purified and washed with deionized water and DMF to remove residual Na 4 PTC and other impurities.…”

Zulys et al [9] explained that the photocatalytic activity of La-PTC depends on the electron-hole recombination process. The conduction band (CB) of La-PTC (-1.60 eV) which less negative than the lowest unoccupied molecular orbital (LUMO) of methylene blue (-0.25 eV), and the valence band (VB) of La-PTC (+0.61 eV) is less positive than highest occupied molecular orbital (HOMO) of MB (+1.66 eV).…”

Isonicotinic acid is a pyridine carboxylic compound that can be used as a linker to construct coordination complexes. Adding isonicotinic acid (HIna) to the metal-organic framework (MOF) enhanced the MOF surface area, pore volume, and pore size and increased its catalytic activity. Ti3C2Tx MXene nanosheet with excellent metal conductivity was also employed on MOF to optimize its functionality. This work aims to synthesize MOF modulated isonicotinic acid La-PTC-HIna and design the new materials: La-PTC/Ti3C2Tx MXene and La-PTC-HIna/Ti3C2Tx MXene hybrid, then apply them for methylene blue photodegradation. La-PTC-HIna, La-PTC/Ti3C2Tx MXene, and La-PTC-HIna/Ti3C2Tx MXene were synthesized by the sonochemical method. MOF La-PTC-HIna has the highest methylene blue photocatalytic degradation activity than MOF La-PTC, Ti3C2Tx MXene, La-PTC/Ti3C2Tx MXene, and La-PTC-HIna/Ti3C2Tx MXene with degradation efficiency of 99.48% in 20 ppm methylene blue under visible irradiation for 210 min. This study reveals the La-PTC-HIna and La-PTC-HIna/Ti3C2Tx MXene as a new material that has the potential to remove methylene blue from an aqueous solution.

Photocatalytic processes are among the prime means for mitigating the pollution caused by toxic effluents. In this context, photocatalysis presents a promising path and is undergoing rapid evolution. Halide perovskite‐nanocrystals (HP‐NCs) are excellent candidates due to their negative conduction band minimum and low work function, essential for photocatalysis. Yet, HP‐NCs face limitations within this domain because they are prone to chemical degradation when exposed to external factors like high temperature, polar solvents, oxygen, and light. A practical approach toward stabilizing HP‐NCs involves hybridizing them with a chemically inert material that can provide steric stabilization and act as a cocatalyst. Transition‐metal dichalcogenides emerge as outstanding candidates to sterically stabilize the HPs as they are stable, chemically inert, and can serve as co‐catalysts, enabling suppressed charge recombination. Herein, the photocatalytic performance of Cs4PbBr6/WS2‐nanocomposites towards organic dye degradation in polar solvents under visible light illumination is investigated. We found that the presence of WS2 nanostructures significantly stabilizes the HP‐NCs and promotes dye degradation rate compared to pristine Cs4PbBr6‐NCs. Using transient absorption measurements, we found that the WS2‐nanostructures act as an electron transport channel, effectively reducing charge recombination in the NCs. These findings pave the way for implementing Cs4PbBr6/WS2‐nanocomposites as stable and superior photocatalysts.
