Abstract This study presents the development of a groundbreaking acetone gas sensor leveraging Cl‐doped ZnO nanodisks, designed to operate efficiently at low temperatures. Through comprehensive experimental and theoretical analyses, they have elucidated exceptional sensing capabilities nanodisks. Both undoped with varying chlorine concentrations were synthesized on Si/SiO 2 substrates using straightforward thermal evaporation method in tube furnace. Notably, morphology pure formed microdisks, whereas transitioned increased Cl doping, it further evolved into nanoplates. X‐ray diffraction x‐ray photoelectron spectroscopy (XPS) confirmed successful substitution oxygen ions ions. Enhanced photoluminescence XPS analyses revealed that contained significantly higher density vacancies compared ZnO. The exhibited an outstanding sensitivity approximately 40 impressive selectivity 55% toward 100 ppm 80°C. doping markedly improved sensor's response recovery times, enabling detection as 225 ppb 80°C—a remarkable achievement unattainable All characterization results strongly indicate play pivotal role enhancing gas‐sensing performance Cutting‐edge functional theory calculations uncovered significant interactions between through charge variations band structure analysis. These resulted notable changes states, including distinct peak near −3 eV, indicating enhanced sensitivity.

Reliable Determination of Polymeric Carbon Nitride Wettability: A Standardized Sessile Drop Method for Pressed-Tablet Samples

Published: Jan. 1, 2024

The wettability of polymeric carbon nitride (PCN) is an important surface chemical factor affecting its catalytic and separation performance. However, due to the amphipathic characteristics hydrophilic/lipophilic porous powder properties, contact angle (CA) PCN measured by common sessile drop method will be interfered substrate, resulting in randomness results. Herein, pristine PCNs obtained thermal polycondensation different precursors air or nitrogen atmosphere were used as research object. CA was a modified after traditional powders replaced pressed-tablet samples. influence sample mass applied pressure on specific area, pore volume, morphology samples investigated carefully, optimal experimental conditions determined. When 0.15g 10MPa, water between 27~34°, diiodomethane 24~29°. measurement results showed considerable stability reproducibility. This improved provides simple standardized way accurately explore chemistry PCN, has potential other hydrophilic/oleophilic materials.
