This Special Issue highlights the latest develop-ments and innovations in the field, featuring a diverse array of research papers that exploreseveral aspects of hydrocarbon oxidation.One example is the first contribution, which delves into hydrocarbon oxidation depthusing the H2O2/Cu2Cl4·2DMG/CH3CN system (contribution 1). This study not onlyelucidate the catalytic mechanism but also provides insights into the efficiency of theoxidation process.The utilization of commercial gold complexes supported on functionalized carbon ma-terials plays a pivotal role in the direct oxidation of ethane into acetic acid (contribution 2).This research showcases the potential of gold-based catalysts in the selective transformationof alkanes into high-value-added chemicals.The intriguing role of PhOH and tyrosine in the selective oxidation of hydrocarbonsadds a new dimension to our understanding of the factors influencing catalytic selectivity(contribution 3). This study offers valuable insights into the details of controlling theoxidation process for optimal product yields.Moving beyond simple hydrocarbons, an investigation into the one-stage catalytic oxi-dation of adamantane to tri-, tetra-, and penta-ols broadens the scope of catalytic oxidationmethodologies (contribution 4). The results presented in this paper open up avenues forthe controlled synthesis of complex oxygenated compounds from hydrocarbons.Studies of nickel/samarium-doped ceria provide essential information for the catalyticpartial oxidation of methane, exploring the role of oxygen vacancy in enhancing catalyticperformance (contribution 5). Similarly, the enhanced performance of OMS-2-supportedCuOx catalysts for the oxidation of carbon monoxide, ethyl acetate, and toluene underscoresthe versatility of these catalysts (contribution 6).The selective catalytic oxidation of toluene into benzaldehyde is investigated witha focus on the effect of aging time and calcination temperature using CuxZnyO mixedmetal oxide nanoparticles (contribution 7). This work contributes valuable insights into theoptimization of catalysts for specific oxidation reactions.Further contributions examine the oxidation of 5-hydroxymethylfurfural on supportedAg, Au, Pd, and bimetallic Pd–Au catalysts, exploring the impact of the support on catalyticactivity (contribution 8). Additionally, a comprehensive study on the reaction mechanismfor methane-to-methanol in Cu-SSZ-13, employing first-principles analysis of the Z2[Cu2O]and Z2[Cu2OH] motifs, expands our understanding of methane oxidation (contribution 9).The application of artificial neural network modeling to increase the efficiency of opti-mized V-SBA-15 catalysts in the selective oxidation of methane into formaldehyde showcasesthe integration of advanced computational methods in catalyst design (contribution 10).This Special Issue also introduces newly isolated alkane hydroxylase and lipase-producing Geobacillus and Anoxybacillus species involved in crude oil degradation(contribution 11). This contributes a biotechnological perspective to the catalytic oxidation ofhydrocarbons, emphasizing the potential of microorganisms in environmental remediation.Catalysts 2024, 14, 111. https://doi.org/10.3390/catal14020111 https://www.mdpi.com/journal/catalystsCatalysts 2024, 14, 111 2 of 2As we navigate the complexities of hydrocarbon oxidation, this collection of re-search papers not only presents the current state of the field but also paves the way forfuture advancements.As Guest Editor for this Special Issue, I express my gratitude to all the contributingauthors and also to the dedicated staff members at MDPI for their important editorialsupport. We look forward to the continued exploration of catalytic processes that drive thesustainable transformation of hydrocarbons.Funding: SACC is grateful to Fundação para a Ciência e a Tecnologia (FCT), Portugal for Scientific Em-ployment Stimulus-Institutional Call (DOI 10.54499/CEECINST/00102/2018/CP1567/CT0026) andto the Associate Laboratory for Green Chemistry-LAQV financed by national funds from FCT/MCTES(UIDB/50006/2020 and UIDP/5006/2020).Data Availability Statement: Not applicable.Conflicts of Interest: The author declares no conflicts of interest.List of Contributions1.
