“…Moreover, when the Ti‐atom‐modified PG system adsorbed multiple CH 4 molecules, the substrate was stable, and the CH 4 molecules were not deformed. Previously, Chen et al [ 45 ] used density functional theory to calculate the adsorption of formaldehyde molecules on Ti‐modified graphdiyne and discovered that the modification of Ti atoms promoted the adsorption of gas molecules on graphdiyne. Xu et al [ 46 ] reported that the adsorption performance of a Ti‐modified graphdiyne for CH 4 improved significantly.…”

Due to the rapid development of science and technology, energy consumption is increasing continually. Traditional fuels such as coal and oil are insufficient for satisfying the long-term development of humans, and fuel burning will generate a significant amount of harmful gases, which will affect the ecological environment and human health. The main component of natural gas is methane (CH 4 ). [1] Although it is not renewable energy, it has become one of the transition fuels of low-carbon energy due to its high reserves and less CO 2 is generated when it is burned, compared with coal, oil, and other fuels. Studies regarding CH 4 have been performed extensively worldwide. CH 4 is a greenhouse gas that constitutes %20% of global warming cases [2] ; therefore, it must be stored appropriately to prevent its leakage into the atmosphere. Hence, researchers are attempting to identify a material that enables large amounts of CH 4 to be stored safely and efficiently. Traditional CH 4 storage methods include liquefied natural gas [3] (LNG), compressed natural gas [4] (CNG), and adsorbed natural gas. Due to the potential safety hazards of LNG and CNG during their transportation, natural gas adsorption technology [5,6] has been vigorously investigated and developed. Currently, typical methane storage materials include primarily molecular sieves, [7] activated carbon, [8] and metal organic frameworks [9,10] (MOFs). Menon and Komarneni [11] reported a linear relationship between CH 4 storage and the material surface area of molecular sieves and other materials, although the adsorption capacity was low. Rozyyev et al. [12] demonstrated a methane reserve of 62.5 wt% at a pressure of 5 to 100 bar for the porous polymer COP-150, which exhibited a certain memory effect. Zhao et al. [13] discovered that under standard conditions, the CH 4 storage of F-modified zirconium-based MOF materials was 16.0 wt%, which afforded high stability. Liang et al. [14] reported a newly synthesized porous metal organic framework ST-2, which can store the same amount of CH 4 at 130 bar and 298 K as that of the CNG process at 250 bar, and the maximum energy storage can reach 289 cm 3 stp cm À3 under specific cases. Liu et al. [15] reported that the maximum CH 4 adsorption capacity of the DUT-49 MOF was 24.0 wt% and discovered that the CH 4 storage capacity was associated significantly with the pore size and surface area of porous materials such as MOFs and covalent organic frameworks. Chen et al. [16] discovered that the simulation-motivated synthesis of ultraporous MOFs based on metal trinuclear clusters, namely, NU-1501-M (M ¼ Al or Fe), satisfied the four Brunauer-Emmett-Teller consistency criteria. It exhibited excellent CH 4 storage performance, and the maximum CH 4 storage capacity of NU-1501-AL was 66.0 wt%. The USA Department of Energy (DOE) Advanced Research Projects Agency for Energy reported that the weight density of on-board energy CH 4 adsorption should exceed 50.0 wt% under standard conditions. [17] Currently, most CH 4 storage materials ...

“…With regard to GDYO, the D and G bands correspond to sp carbons as well as sp 2 and sp 3 arising from defects and some oxides, resulting from the oxidation of the material. Thus, the peptide can interact with the micromotor 2D surface via π interactions. ,, In the case of BP, the characteristic phonon modes (A g 1 , A g 2 , and B 2g ) are presented, indicating the successful incorporation into the micromotor. , As each phosphorus atom is bonded to three adjacent phosphorus atoms, sp 3 hybridization occurs, with the “p” orbital retaining a lone pair of electrons.…”

In this work, we study the interaction of graphdiyne oxide (GDYO)-, graphene oxide (GO)-, or black phosphorous (BP)-wrapped Janus micromotors using a model system relying on a fluorescencelabeled affinity peptide, which is released upon specific interaction with a target Cholera Toxin B. Such ON−OFF−ON system allows mimicking similar processes occurring at (bio)-interfaces and to study the related sorption and desorption kinetics. The distinct surface properties of each nanomaterial play a critical role in the loading/release capacity of the peptide, greatly influencing the release profiles. Sorption obeys a secondorder kinetic model using the two-dimensional (2D) nanomaterials in connection with micromotors, indicating a strong influence of chemisorption process for BP micromotors. Yet, release kinetics are faster for GDYO and GO nanomaterials, indicating a contribution of π and hydrophobic interactions in the probe sorption (Cholera Toxin B affinity peptide) and target probe release (in the presence of Cholera Toxin B). Micromotor movement also plays a critical role in such processes, allowing for efficient operation in low raw sample volumes, where the high protein content can diminish probe loading/release, affecting the overall performance. The loading/release capacity and feasibility of the (bio)-sensing protocol are illustrated in Vibrio cholerae and Vibrio parahaemolyticus bacteria cultures as realistic domains. The new concept described here holds considerable promise to understand the interaction of micromotor with biological counterparts in a myriad of biomedical and other practical applications, including the design of novel micromotor-based sensors.

“…Sc or Ti take a stable place on the corner sites of graphdiyne sheets, and both can better adsorb HCHO compared with pristine graphdiyne and graphene. This effect would be due to the electronegativity of HCHO, and the best result is with Ti-decorated graphdiyne, according to DFT calculations [ 165 ].…”

The adsorption of molecules usually increases capacity and/or strength with the doping of surfaces with transition metals; furthermore, carbon nanostructures, i.e., graphene, carbon nanotubes, fullerenes, graphdiyne, etc., have a large specific area for gas adsorption. This review focuses on the reports (experimental or theoretical) of systems using these structures decorated with transition metals for mainly pollutant molecules’ adsorption. Furthermore, we aim to present the expanding application of nanomaterials on environmental problems, mainly over the last 10 years. We found a wide range of pollutant molecules investigated for adsorption in carbon nanostructures, including greenhouse gases, anticancer drugs, and chemical warfare agents, among many more.
