“…In this context, the combination of CPs with metal nanostructures has generated great curiosity due to their unique optical, electrical, mechanical, and electrochemical properties (Kumar et al, 2019;Nath et al, 2019). Their applications in various areas including catalysis, detection, medical, nanotechnology, and environment have been largely explored (Oularbi, 2018;Oularbi et al, 2019Oularbi et al, , 2020Chauhan et al, 2020;El Attar et al, 2020;Kanaujia et al, 2020). CPs have been widely combined with various metal-based nanostructures such as Pt, Pd, Au, Cu, Ni, Fe 3 O 4 , TiO 2 , WO 3 , SnO 2 , MoS 2 , and MnO 2 (Cho et al, 2011;Wang et al, 2012;Dimitrijevic et al, 2013;Lei et al, 2015;Razzaghi et al, 2015;Li et al, 2016aLi et al, , 2016bLin et al, 2016;Yan et al, 2018;Nath et al, 2019;Kanaujia et al, 2020), with different morphologies and structures.…”

Sustainable energy development is a major challenge, particularly when considering population increase, rising energy demands resulting from the excessive use of nonrenewable fossil fuels, and growing consequences on global pollution and climate change. It is critical to continue to develop new sources of renewable and clean energy. Direct alcohol fuel cell (DAFC) represents a technological approach that meets all the requirements in terms of energy conversion with good electrical efficiency and lower emissions of pollutants. However, it largely suffers from the poisoning of the anode catalyst caused by the accumulation of intermediate products. In this context, this review is devoted to discussing the recent progress in anode catalysts based on conducting polymers (CPs) materials for direct alcohol fuel cells, especially direct methanol and ethanol fuel cells, from the viewpoint of synthesis techniques, morphology, and catalytic performance. In the first part of this review, we will explore the most commonly used methods for preparing metal-conducting polymer-based nanocomposites, including the key factors influencing their morphology regardless of the application. The catalytic performances of mono-, bi-, and tri-metal catalysts deposited on conducting polymer-based supports for the electrooxidation of methanol and ethanol reactions are examined in detail in the second and third parts of this review. We also highlight the effect of the introduction of carbon nanomaterials into conducting polymer supports on the electrical properties and on the performance of the catalysts. Development of anode materials using nanostructured conducting polymers-based support plays a vital role in reducing catalyst loadings and should therefore shed light on the wide-scale commercialization of DAFCs. In a nutshell, this review will give readers a thorough understanding of the principles of direct alcohol fuel cells, new advancements in electrode materials based on non-precious metals, and the main challenges that should be dealt with.

“…The crystal packing of self-assembled hybrids depends on the nature and conformation of organic moieties (R–NH 2 ), while the organic moieties react with the parental layered inorganic semiconductor (PbI 2 ). ,,,− The thin-film X-ray diffraction (XRD) patterns of fabricated cyclic ammonium-based IO hybrid thin films confirm their structural packing and layered arrangement (Figure ). The crystallographic study of primary cyclic ammonium series ( n = 3–8)-based IO hybrid semiconductors has been reported previously by Billing and Lemmerer, and the thin-film XRD results were verified with the single-crystal XRD data.…”

This work reports the synthesis, structural, linear, and nonlinear optical investigations into low-dimensional naturally selfassembled inorganic−organic (IO) hybrid systems based on (C n H 2n−1 NH 3 ) + (n = 3−8) cyclic moieties. The steric effects of cyclic ring sizes convert the IO hybrids from two-dimensional (2D) layered structures to 1D crystal packing. The crystal packing of this class of IO hybrid compounds of cyclic sizes from n = 3 to 6 shows a perfect 2D layered structural arrangement having a crystal structure (R−NH 3 ) 2 PbI 4 . On the contrary, n = 7 hybrid shows a 1D layered structural arrangement, but the adjacent chains are disconnected along the "c"-axis, resulting into (R−NH 3 ) 3 PbI 5 . Moreover, for n = 8 hybrids, the inorganic network structure is infinitely extended along the "a"-axis having (R−NH 3 )PbI 3 1D crystal structure. These structural changes may lead to defect states, which is verified by density functional theory (DFT) calculations. The linear and nonlinear optical probing of room-temperature optical excitons demonstrate the photoluminescence and absorption feature variation from 2D layered crystal packing (n = 3−6) to quasi-1D structures (n = 7, 8). A systematic correlation of one-photon (1PA)-and two-photon (2PA)-excited exciton photoluminescence (PL) features with a cyclic size is discussed and presented. While one-photon absorption-induced photoluminescence (1PA-PL) provides information about strong exciton emission from the top few perfectly aligned layers, twophoton excitation probes the deeper depths. This shows red-shifted PL (2PA-PL) from the structurally distorted crystal packing within the sample and traces of defect-induced emission. The DFT study shows that the I-vacancy defect creates the states at conduction band minimum (CBm), which leads to a sudden reduction in the band gap for n = 7 and 8. The systematic optical probing studies to determine the structural deviations in IO hybrid semiconductors will provide a new platform for advanced photonics and optoelectronic devices.
