Wastewater from many sectors that contains hazardous organic pollutants exacerbates environmental contamination. Consequently, outstanding photocatalytic substances can successfully degrade are needed to provide pollution-free water. From this perspective, zinc oxide/g-C3N4-based composites desirable due their low cost, strong reactivity, and friendliness. So, in the current investigation, sequ...

This study focused on the modification of graphitic carbon nitride (g-C3N4) using which was obtained from pyrolysis coconut shell husk. The sonocatalytic performance synthesized samples then studied through degradation malachite green. In this work, pure g-C3N4, and carbon/g-C3N4 composites (C/g-C3N4) at different weight percentages were prepared characterized by XRD, SEM-EDX, FTIR, TGA surface...

Modification of nickel sulfide cocatalysts is considered to be a promising approach for efficient enhancement the photocatalytic hydrogen production performance g-C3N4. Providing more NiS cocatalyst function as active sites g-C3N4 still highly desirable. To realize this goal, in work, facile sulfur-mediated photodeposition was developed. Specifically, photogenerated electrons excited by visible...

Ultraviolet position-sensitive detectors (PSDs) are expected to undergo harsh environments, such as high temperatures, for a wide variety of applications in military, civilian, and aerospace. However, no report on relevant PSDs operating at temperatures can be found up now. Herein, we design new 2D/3D graphitic carbon nitride (g-C3N4)/gallium (GaN) hybrid heterojunction construct the ultraviole...

Amphiphilic carbon nitride (g-C3N4) was decorated onto reduced graphene oxide (rGO) to obtain rGO-g-C3N4 composites as excellent adsorbents for the removal of aromatic organic compounds from industrial wastewater. The obtained are effective due amphiphilic g-C3N4. We propose a new adsorption model using an additive which can enhance water accessibility and hydrophobic interactions between rGO w...

For the first time, it is demonstrated that the robust organic semiconductor g-C3N4 can be integrated into a nature-inspired water splitting system, analogous to PSII and PSI in natural photosynthesis. Two parallel systems have been developed for overall water splitting under visible light involving graphitic carbon nitride with two different metal oxides, BiVO4 and WO3. Consequently, both hydr...

Graphitic carbon nitride (g-C3N4) is a promising heterogeneous photocatalyst in the visible range. It can be used, among others, for reductive conversion of toxic hexavalent chromium occurring various wastewaters. Its photocatalytic efficiency, however, has to improved, which realized by modification with different dopants or co-catalysts forming heterojunctions. In our work, ruthenium-modified...
