“…César Leyva Porras et al [31] elucidated how DSC is employed for investigating intricate solid-solid and liquid-liquid interactions in food and medicines. There are also pertinent studies [32] highlighting the use of DSC in the characterization of graphene-based materials and understanding of solid surface state at the molecular scale. Due to its own inherent characteristics, DSC predominantly focuses on the characterization of solid materials and its application in studying solid-liquid interface interactions is comparatively rare.…”

Solid–liquid interfacial phenomena play an essential role in our everyday lives and are often regarded as the outcome of interactions at the solid–liquid interface. However, the intricately intrinsic mechanism underlying interfacial interactions renders in situ simulations and direct measurements challenging. As an effective analytic method for studying solid–liquid interfacial interactions, microcalorimetry can provide the most basic thermodynamic information (including changes in enthalpy, entropy, and Gibbs free energy during solid–liquid binding/separation processes), which is extremely crucial for understanding interaction directionality and limitation. This review is dedicated to highlighting the pivotal role of microcalorimetry in studying solid–liquid immersion and adsorption processes. Specifically, we provide an overview of the commonly employed microcalorimetric methods, including differential scanning calorimetry (DSC), isothermal titration calorimetry (ITC), and immersion microcalorimetry (IM), and delve into the influence factors of enthalpy change, and finally discuss the specific applications of microcalorimetry in studying various solid–liquid binding processes. There remains a vast expanse of thermodynamic information regarding solid–liquid interactions that await exploration via calorimetry.

“…In argon/hydrogen atmosphere, the mass started to increase above 200 • C, along with an endothermic peak on the DTA curve, suggesting the hydrogenation of the aromatic rings, with a maximum increase in mass of 0.53%. This process stopped at around 260 • C, and the mass began to decrease, as the decomposition continued; however, the mass loss in the end was the smallest, i.e., only 2.67% [34][35][36].…”

Investigating the Reduction/Oxidation Reversibility of Graphene Oxide for Photocatalytic Applications

The aim of the study was to analyze the reversibility of the cycle of graphene oxide (GO), reduced GO, and GO obtained by consecutive reoxidation of reduced GO. Accordingly, GO was heated in three different atmospheres (oxidizing, inert, and reducing, i.e., air, nitrogen, and argon/hydrogen mixture, respectively) at 400 °C to obtain reduced GO with varying composition. The bare GO and the RGO samples were oxidized or reoxidized with HNO3. The thermal properties, composition, bonds, and structure of the samples were investigated with TG/DTA, EDX, Raman spectroscopy, and XRD. Their photocatalytic activity was tested by decomposing methyl orange dye under UV light irradiation.
