摘要

红外光谱已被广泛用于表征碳酸盐的结构和振动性质，但其在研究碳酸盐表面吸附能力方面的应用仍然有限。这篇简短的综述介绍了FTIR作为研究碳酸盐结构和表面化学的有力工具的使用，这与一些环境和工业应用（如CO 2捕获）有关。几种FTIR技术提供了碳酸盐多晶物（方解石、文石、水晶石和非晶相）结构及其相变动力学的详细分析。此外，还进行了各种分子（CO、CO₂、H₂O、酸和几种hc）的吸附研究，以确定吸附位点、机理和中间体。这些见解强调了红外光谱对理解碳酸盐结构和表面性质的重要性，并指导了未来在涉及碳酸盐的几种环境和工业过程中的研究。

Infrared spectroscopy at the surface of carbonates

IR spectroscopy has been extensively employed to characterize the structural and vibrational properties of carbonates, yet its application in studying adsorption capacity of carbonate surfaces remains limited. This short review presents the use of FTIR as a powerful tool for investigating the structure and surface chemistry of carbonates, which is relevant to several environmental and industrial applications (such as CO₂ capture). Several FTIR techniques provide detailed analysis of the structure of carbonate polymorphs (calcite, aragonite, vaterite, and amorphous phases) alongside their phase transformation kinetics. In addition, adsorption studies of various molecules (CO, CO₂, H₂O, acids and several HCs) were performed to identify the adsorption sites, mechanisms and intermediates. These insights highlight the significance of IR spectroscopy for understanding carbonate structure and surface properties, and guide future research in several environmental and industrial processes where carbonates are involved.

期刊介绍： Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
