“…Previously, luffa sponge has been successfully used in many applications such as bio‐fibers manufacturing, [ 73 ] bio‐sorbent to the removal of divalent metals, oil absorption, CO 2 chemical fixation, [ 74 ] efficient phenol degradation, [ 72 ] composite materials [ 75 ] and also in Li‐ion batteries. [ 76,77 ] To the best of our knowledge, no application of candle soot coated luffa sponge as the material for solar photothermal conversion has been demonstrated till now.…”

energy sector's two-superseding obstacles on the road to a sustainable future. [1][2][3] As the proven reserves of fossil fuels decrease, renewable energy sources have been sought in high demand, of which solar power is the most promising and potentially limitless source of energy in the foreseeable future. The energy from the sun to the earth is as high as 3 × 10 24 Jules per year, just 0.1% of the total solar resource would be sufficient to satisfy the annual worldwide energy demand. At present, solarsteam generation, which particularly refers to solar vapor under 100 °C, is considered to be one of the most promising sectors among other solar energy harvesting technologies owing to its potential applications in modern power plants, chemical plants, liquid-liquid phase separation, water purification and desalination, wastewater treatment, and many others. [4,[7][8][9][10][11][12][13][14] Among which water purification and desalination are gaining a lot of interest due to the recent lack of drinkable clean water supplies across the globe. Other competitive technologies for the production of freshwater, such as solid-liquid extraction, [13,15] electrochemical analysis [16,17] membrane-based separation, [18,19] etc. have many drawbacks, including high energy usage, possible environmental emissions, high infrastructure capital costs, etc.However, the efficiency of the traditional solar-steam generation method is below 24%, even with a high optical concentration ratio. [20] The traditional approach involves water evaporation by converting solar radiation directly to heat for steam generation commonly by using bulk metals. These bulk metals are inefficient in absorbing the solar spectrum and transferring heat through bulk water. As a consequence, its performance is limited by localized heat generation and transfer losses. [12,20,21] By contrast, interfacial solar vapor generation (ISVG) can localize the heat on the evaporation surface and, rather than the whole water, selectively heating the evaporation portion to minimize heat transfer to the water and significantly increase the solar evaporation efficiency. Therefore, ISVG has emerged as a novel concept for the solar steam generation with higher efficiency, attributes to the recent developments in nanoscale structural design with efficient photon and thermal management known as photothermal conversion materials. [1,[22][23][24][25][26] The photothermal conversion materials should have strong solar absorption and low thermal conductivity to achieve greater efficiency. [6,12] Moreover, it is also desirable to have superior hydrophilicity and porosity for fast water and A chemically treated luffa sponge (LS) derived from the ripe fruit of the Luffa cylindrica (LC) plant is investigated as an efficient solar photothermal conversion material for water purification applications for the very first time. Hydrophilicity and solar absorbance of the LS are enhanced by dopamine treatment and candle soot surface coating. The fabricated surface modified LS (SM-LS) leads to a sup...

“…Figure S4a, Supporting Information, shows the Raman spectrum of TiN NFs@rGO, the intensity ratio of graphitic peak and graphitic defects peak was about 1.07, indicating a good crystallinity of graphene. [ 26 ] The sulfur content in S/TiN NFs@rGO achieved 79%, which was confirmed by TGA (Figure S4b, Supporting Information). The specific surface area decreased from 143 to 6.2 m 2 g −1 and the pore size reduced from 2.8 to 1.9 nm after sulfur loading, indicating the full loading of sulfur in TiN NFs@rGO (Figure S4c,d, Supporting Information).…”

The design of nanomaterials with grain orientation structure by crystal facet engineering is of great significance for boosting the catalytic ability and electrochemical properties, but the controllable synthesis is still a challenge. Here, TiN nanoflakes with exposed (001) facets are prepared using 2D Ti3C2 MXene as the initial reactant and applied as a bidirectional electrocatalyst for the reduction and oxidation process in lithium‐sulfur batteries (LSBs). The (001) facet‐dominated TiN nanoflakes have a strong adsorption capacity for soluble lithium polysulfides (LiPSs). More importantly, theoretical calculations and experiment results confirm the (001) facet‐dominated TiN nanoflakes catalyze the conversion of soluble LiPSs to Li2S2/Li2S to induce the Li2S uniform deposition in the discharge process and decrease the delithiation barrier of Li2S in the charge process. Therefore, the excellent electrochemical properties of LSBs are achieved, which demonstrates a high discharge capacity of 949 mAh g−1 at 1 C and maintains high capacity reversibility with a decay rate of 0.033% per cycle after 800 cycles.

“…The comparison is shown in Table . The reversible capacity of the current sample is also higher than other transition metal oxide based anodic materials reported in the previous works, such as the molybdenum‐doped titanium dioxide, the MoO 2 /C hybrid microspheres, the porous Co 3 O 4 /CuO composite, the SnO 2 @TiO 2 composite and the SnO 2 @C composite . It is obvious that the present nanotubular MoO 3 ‐48.9%−SnO 2 composite shows excellent lithium storage performance.…”

A hierarchically nanotubular MoO 3 /SnO 2 composite was synthesized based on the layer-by-layer self À assemble process followed by a calcination treatment, employing natural cellulose substance (commercial filter paper) as structural scaffold. This nanocomposite is composed of molybdenum trioxide nanocrystallites immobilized as a thin layer on the tin oxide nanotube surface. As being utilized as a host material for lithium storage, the MoO 3 /SnO 2 nanocomposite exhibited high reversible specific capacity, good cyclability and enhanced rate performance as compared with the pure SnO 2 and MoO 3 counter materials. For the nanotubular MoO 3 /SnO 2 composite with 48.9 wt% MoO 3 content, it delivered an initial discharge capacity of 1930.6 mAh g À 1 and a stable specific capacity of 1084.1 mAh g À 1 after 100 discharge/charge cycles at a current density of 100 mA g À 1 . The excellent lithium storage performance of the MoO 3 /SnO 2 composite is benefited from the sophisticated hierarchically three-dimensional network structures and the synergistic interaction between MoO 3 and SnO 2 components upon repeated lithiation/delithiation processes.[a] Dr.
