“…The Pd-CNT-rGO nanocomposite is suspended in a PEDOT:PSS solution to create a soluble ink that can be absorbed by the paper fibers. The composite effectively combines rGO, CNT, and Pd to create a synergistic effect, producing a material with exceptional conductivity, rapid electron capture/transport capabilities, stable catalytic activity, and a high surface area. − The rGO contributes its excellent conductivity, superior electron transport capabilities, and catalytic interactions, but graphene can face an issue of excessive aggregation and stacking interactions, limiting the surface area and reducing catalytic sites. The Pd nanoparticles, which are additionally quite conductive and catalytically active, prevent aggregation of graphene to maintain the material’s high surface area.…”

Humanity's excessive production of material waste poses a critical environmental threat, and the problem is only escalating, especially in the past few decades with the rapid development of powerful electronic tools and persistent consumer desire to upgrade to the newest available technology. The poor disposability of electronics is especially an issue for the newly arising field of singleuse devices and sensors, which are often used to evaluate human health and monitor environmental conditions, and for other novel applications. Though impressive in terms of function and convenience, usage of conventional electronic components in these applications would inflict an immense surge in waste and result in higher costs. This work's primary objective is to develop a cost-effective, eco-friendly, all-paper, device for single-use applications that can be easily and safely disposed of through incineration or biodegradation. All electronic components are paper-based and integrated on paper-based printed circuit boards (PCBs), innovatively providing a realistic and practical solution for green electronic platforms. In particular, a methodology is discussed for simultaneously achieving very tunable resistors (20 Ω to 285 kΩ), supercapacitors (∼3.29 mF), and electrolyte-gated field-effect transistors on and within the thickness of a single sheet of paper. Each electronic component is completely integrated into functionalized paper regions and exhibits favorable electrical activity, adjustability, flexibility, and disposability. A simple amplifier circuit is successfully demonstrated within a small area and within the thickness of a single sheet of paper, displaying component versatility and the capability for their fabrication processes to be performed in parallel for efficient and rapid development.

“… The relatively high overpotential, low current densities, and inferior long-term stability are critical barriers in gCNs for HERs, which cannot meet practical requirements (i.e., current density up to several ambers and durability for several weeks or months). This could be solved using noble metal dopants in the formation of heterojunction structures with porous metal oxynitride [ 165 , 166 ], multimetallic nanocrystals [ 12 , 167 , 168 ], MXenes [ 2 , 169 , 170 , 171 , 172 ], MOF [ 10 , 173 , 174 ], graphene [ 175 ], and graphdiyne [ 176 ] to augment solar light harvesting and charge carrier separation during the HER. The safety of H 2 storage tanks should be considered because in the case of unexpected accidents, the H 2 tank becomes a bomb.…”

Photocatalytic green hydrogen (H2) production through water electrolysis is deemed as green, efficient, and renewable fuel or energy carrier due to its great energy density and zero greenhouse emissions. However, developing efficient and low-cost noble-metal-free photocatalysts remains one of the daunting challenges in low-cost H2 production. Porous graphitic carbon nitride (gCN) nanostructures have drawn broad multidisciplinary attention as metal-free photocatalysts in the arena of H2 production and other environmental remediation. This is due to their impressive catalytic/photocatalytic properties (i.e., high surface area, narrow bandgap, and visible light absorption), unique physicochemical durability, tunable electronic properties, and feasibility to synthesize in high yield from inexpensive and earth-abundant resources. The physicochemical and photocatalytic properties of porous gCNs can be easily optimized via the integration of earth-abundant heteroatoms. Although there are various reviews on porous gCN-based photocatalysts for various applications, to the best of our knowledge, there are no reviews on heteroatom-doped porous gCN nanostructures for the photocatalytic H2 evolution reaction (HER). It is essential to provide timely updates in this research area to highlight the research related to fabrication of novel gCNs for large-scale applications and address the current barriers in this field. This review emphasizes a panorama of recent advances in the rational design of heteroatom (i.e., P, O, S, N, and B)-doped porous gCN nanostructures including mono, binary, and ternary dopants for photocatalytic HERs and their optimized parameters. This is in addition to H2 energy storage, non-metal configuration, HER fundamental, mechanism, and calculations. This review is expected to inspire a new research entryway to the fabrication of porous gCN-based photocatalysts with ameliorated activity and durability for practical H2 production.

“…Two-dimensional (2D) materials, including graphene, black phosphorus (BP), transition metal dichalcogenides (TMDs), layered double hydroxides (LDHs), transition metal carbides and nitrides (MXenes) have attracted extensive attention of the scientific community for their unique chemical and physical property [1] , [2] , [3] , [4] , [5] , [6] , [7] . Among these 2D materials, MXenes have aroused huge research upsurge in terms of the synthesis and application since its first discovery in 2011 by Yury Gogotsi [8] , [9] , [10] , [11] .…”
