Density functional theory (DFT) computations apply to physics, chemistry, material science, and engineering. In chemical engineering, DFT identifies material structure and properties, and mechanisms for phenomena such as chemical reaction and phase transformation that are otherwise impossible to measure experimentally. Even though its practical application dates back only a decade or two, it is already a standard tool for materials modelling. Many textbooks and articles describe the theoretical basis of DFT, but it remains difficult for researchers to autonomously learn the steps to accurately calculate system properties. Here, we first explain the foundations of DFT in a way accessible to chemical engineers with little background in quantum mechanics or solid‐state physics. Then, we introduce the basics of the computations and, for most of the rest of the article, we show how to derive physical characteristics of interest to chemical engineers: elastic, thermodynamic, and surface properties, electronic structure, and surface and chemical reaction energy. Finally, we highlight some limitations of DFT; since these calculations are approximations to the Schrödinger equation, their accuracy relies on choosing adequate exchange‐correlation functions and basis sets. Since 1991, the number of articles WoS has indexed related to DFT has increased quadratically with respect to time and now numbers 15 000. A bibliometric analysis of the top 10 000 cited articles in 2018 and 2019 classifies them into four clusters: adsorption, graphene, and nanoparticles; ab initio molecular dynamics and crystal structure; electronic structure and optical properties; and total energy calculations and wave basis sets.

“…Based on the preceding experiment, adsorption kinetics experiments were conducted to evaluate the adsorption properties of the as-prepared adsorbents by mixing 0.5 g of the as-prepared adsorbents in asks containing 200 mL of 100 mg L À1 NH 4 + -N solution with continuous shaking at the optimum pH value for 24 h. The concentration of NH 4 + -N solution was determined periodically at designated different time intervals. The pseudo-rst-order, pseudo-second-order, and intra-particle diffusion models were employed to analyze the kinetic mechanism of the adsorption process, which can be expressed as follows: 19 Pseudo-rst-order…”

“…Besides, PMS, for example, has a low utilization rate due to the limitations of poor invertibility of transition metals. The singlet oxygen ( 1 O 2 ) dominates the non-radical pathway 12,13,14,15 . Especially for carbonaceous materials, 1 O 2 produced by PMS selfdecomposition is the main active species for degradation 16 .…”

Introducing the anion intermediate found with PTCDA into advanced oxidation processes (AOPs) overcomes the limitation of visible-light degradation. Stabilized PTCDA anionic intermediates act as electron reservoir to activate PMS to generate reactive oxygen species, thus improving the degradation rate of organic pollutants driven by visible light. At the same time, the photogenerated holes of PDI induce α and β scission with the unshared electron in organic molecules, and realize the deep mineralization of converting organic molecules to CO2. The BPA degradation rate of PTCDA /PMS is over 125.8 and 2.8 times as high as PTCDA photocatalysis and Co3O4/PMS, respectively. The BPA mineralization of PTCDA /PMS reaching ~ 88% outclasses Co3O4/PMS (~ 25%). In continuous flow reactor, it has a ~ 100% degradation and ~ 80% mineralization of BPA. The outstanding degradation in real water under solar light excitation indicates that PTCDA/PMS would be an intriguing system for non-toxic and harmless elimination of organic pollutants.
