Doping Carbon Nitride Quantum Dots into Melamine‐Silver Matrix: An Efficient Photocatalyst with Tunable Morphology and Photocatalysis for H2O2 Evolution under Visible Light

“…Besides, it should be pointed out that when the CN QDs @MA−Ag nanocomposites were applied for the photocatalytic splitting of water for H 2 O 2 evolution under sunlight, the enhanced absorption could be observed for the used nanocomposites showing the broadened UV‐vis diffuse emission in the visible region (Figure A, insert), due to that nano‐scaled Ag might be increasingly formed during the illumination procedure. Importantly, such a broadening of the visible‐light response region of nanocomposites would help to further improve their light harvesting or the utilization efficiency of solar energy, as confirmed elsewhere for other kinds of photocatalysts …”

“…Importantly, such a broadening of the visible-light response region of nanocomposites would help to further improve their light harvesting or the utilization efficiency of solar energy, as confirmed elsewhere for other kinds of photocatalysts. [36][37][38] In addition, a comparison of the FTIR spectra was conducted among the CN QDs @MAÀ Ag nanocomposites, CN QDs , and MAÀ Ag nanocomposites ( Figure 5B). It is found that all of the samples could possess the peaks ranging from 1200 to 1650 cm À 1 that may belong to the typical stretching modes of CÀ N heterocycles.…”

Element-doped graphitic carbon nitride: confirmation of doped elements and applications

“…The XPS peak of Fe 2p 3/2 at ~710.5 eV, which lies within the range of the binding energy of Fe 3+ valance state (710.3-711.8 eV), 89 indicates the presence of Fe 3+ in Fe/g-CN. Fe 3+ can also exist in the composites of g-CN and iron species, 90 so more evidence of doping should be provided: the absence of iron species can be observed via the X-ray diffraction (XRD) patterns of Fe/g-CN samples; 30 elemental mapping is also utilized to display the uniform distribution of Fe atoms in Fe/g-CN, namely the successful doping of Fe. 91 To facilitate further researches of g-CN doping, we summarize the reported bond types or oxidation states of heteroatoms and their XPS peak positions in element-doped g-CN materials in Table 1.…”

Tuned S-Scheme Cu2S_TiO2_WO3 Heterostructure Photocatalyst toward S-Metolachlor (S-MCh) Herbicide Removal

“…The driving force responsible of the charge migration is represented by the internal electric field established between the heterostructure components [ 19 , 20 ]. The photogenerated charges are separated in space, based on the semiconductors potential: the holes are located in the conduction band (CB) of the reduction photocatalyst and the electrons are in the valence band (VB) of the oxidation photocatalyst, respectively [ 21 , 22 ]. The photocatalytic reactions generating the (super)oxidative (•OH, •O 2 − ) species are initiated by the photogenerated holes and electrons.…”
