In this study, Gupta et al. prepared a robust multi-purpose NIR-active hydrogel composite using covalently cross-linked with bacterial cellulose matrix. The c-BC@N-LCDs displays a high evaporation rate of 2.2 kg m-2 h-1 under 1 kW m-2. This work could be accepted in Materials Horizons. The suggestions are as follows,
(1) The conversion efficiency is higher than 100%, why?
(2) As shown in Figure 4c, the removal efficiency of Co2+ is much lower than other ions, please explain.
(3) Some recent studies on the solar steam generation should be discussed or compared, for example, Carbon Energy 2023, 5 (11), e331; Exploration 2022, 2 (4), 20220054; Carbon Neutrality 2023, 2 (1), 11.
(4) The references should be checked, for example reference 24
(5) Figure 3e, what is ater?

The authors have made a good revision, and the manuscript could be accepted in the current form.
